Here are some basic principles and explanations to better understand the Internet and mainly domain names.
We will examine more closely the following aspects:The IP addressEach computer and each domain name to its IP address. Let us examine more closely the workings of the IP addressDNS serversEach address has an IP address, how to link the domain name and IP address?


The IP address
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.
The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.
Types of IP
The IP address can bepermanent (fixed IP), typically for servers that "host" websitesor non-permanent (dynamic IP), (private)Dynamic IP:Generally, when you connect to the Internet, your povider (Internet provider) automatically assigns you an IP address. In this case the address is not permanent and each new connection a new address assigned to you. Why? For two reasons:Due to securityKnowing that the IP address is used by hackers (those big bad bearded, you know, right?) To infiltrate other computers, if someone finds your IP address by chance on the Net, it will not you persecute to life, because your address changes each connection and it will be impossible for him to find you every time.Availability AddressIP addresses are still a limit and can not be attributed to infinity as the maximum figure is 255,255,255,255. The organization responsible for assigning IP addresses is the IANA (Internet Assigned Numbers Authority), American Association which among other things, addressing delegates at the European RIPE (European IP Networks). However a change in the protocol is about to be investigated but until the powers are controlled.Fixed IP:A second possibility is that the IP address is permanent (fixed IP).The static IP has the advantage that it allows a server constantly connected to the network. Its disadvantages are the relative loss of anonymity and be the easier prey of pirates (hackers). The fixed IP, today often pay, will tend to develop.
Thus, you have a permanent IP address or not, it lets you communicate on the Internet and identifies you on this one. And to prove that we are at your Current passing through here, here is your IP address:!
DNS servers
DNS = Domain Name Server = server domain name
We have seen that computers work with numbers (IP addresses).However, when you visit a site you insert its address (URL) and not its IP address. How the bond, then, is it done?
These are the DNS servers (Web address directory which was introduced in the late eighties) who are responsible for the correspondence between a domain name (virtual address) and IP address (physical address) .
The organization responsible for managing the DNS is the IANA (Internet Assigned Numbers Authority).
Here's how it unfolds this step in detail, when searching for a domain name such as www.yahoo.com:
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.

The IP address
A domain name is the address of a website on the Internet.Internet is a network of computers. In the world of computers each computer is identified by a number, called an IP address, just like us with our address or our phone number.
The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).

The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.
Types of IP
The IP address can bepermanent (fixed IP), typically for servers that "host" websitesor non-permanent (dynamic IP), (private)Dynamic IP:Generally, when you connect to the Internet, your povider (Internet provider) automatically assigns you an IP address. In this case the address is not permanent and each new connection a new address assigned to you. Why? For two reasons:Due to securityKnowing that the IP address is used by hackers (those big bad bearded, you know, right?) To infiltrate other computers, if someone finds your IP address by chance on the Net, it will not you persecute to life, because your address changes each connection and it will be impossible for him to find you every time.Availability AddressIP addresses are still a limit and can not be attributed to infinity as the maximum figure is 255,255,255,255. The organization responsible for assigning IP addresses is the IANA (Internet Assigned Numbers Authority), American Association which among other things, addressing delegates at the European RIPE (European IP Networks). However a change in the protocol is about to be investigated but until the powers are controlled.Fixed IP:A second possibility is that the IP address is permanent (fixed IP).The static IP has the advantage that it allows a server constantly connected to the network. Its disadvantages are the relative loss of anonymity and be the easier prey of pirates (hackers). The fixed IP, today often pay, will tend to develop.
Thus, you have a permanent IP address or not, it lets you communicate on the Internet and identifies you on this one. And to prove that we are at your Current passing through here, here is your IP address:!
DNS servers
DNS = Domain Name Server = server domain name
We have seen that computers work with numbers (IP addresses).However, when you visit a site you insert its address (URL) and not its IP address. How the bond, then, is it done?
These are the DNS servers (Web address directory which was introduced in the late eighties) who are responsible for the correspondence between a domain name (virtual address) and IP address (physical address) .
The organization responsible for managing the DNS is the IANA (Internet Assigned Numbers Authority).
Here's how it unfolds this step in detail, when searching for a domain name such as www.yahoo.com:
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.
Here are some basic principles and explanations to better understand the Internet and mainly domain names.

DNS servers
DNS = Domain Name Server = server domain name
We have seen that computers work with numbers (IP addresses).However, when you visit a site you insert its address (URL) and not its IP address. How the bond, then, is it done?
These are the DNS servers (Web address directory which was introduced in the late eighties) who are responsible for the correspondence between a domain name (virtual address) and IP address (physical address) .
The organization responsible for managing the DNS is the IANA (Internet Assigned Numbers Authority).
Here's how it unfolds this step in detail, when searching for a domain name such as www.yahoo.com:
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.
Here are some basic principles and explanations to better understand the Internet and mainly domain names.
We will examine more closely the following aspects:The IP addressEach computer and each domain name to its IP address. Let us examine more closely the workings of the IP addressDNS serversEach address has an IP address, how to link the domain name and IP address?

The IP address
A domain name is the address of a website on the Internet.Internet is a network of computers. In the world of computers each computer is identified by a number, called an IP address, just like us with our address or our phone number.
The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.

DNS servers
DNS = Domain Name Server = server domain name
We have seen that computers work with numbers (IP addresses).However, when you visit a site you insert its address (URL) and not its IP address. How the bond, then, is it done?
These are the DNS servers (Web address directory which was introduced in the late eighties) who are responsible for the correspondence between a domain name (virtual address) and IP address (physical address) .
The organization responsible for managing the DNS is the IANA (Internet Assigned Numbers Authority).
Here's how it unfolds this step in detail, when searching for a domain name such as www.yahoo.com:
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.
Here are some basic principles and explanations to better understand the Internet and mainly domain names.
We will examine more closely the following aspects:The IP addressEach computer and each domain name to its IP address. Let us examine more closely the workings of the IP addressDNS serversEach address has an IP address, how to link the domain name and IP address?

The IP address
A domain name is the address of a website on the Internet.Internet is a network of computers. In the world of computers each computer is identified by a number, called an IP address, just like us with our address or our phone number.
The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.
Types of IP
The IP address can bepermanent (fixed IP), typically for servers that "host" websitesor non-permanent (dynamic IP), (private)Dynamic IP:Generally, when you connect to the Internet, your povider (Internet provider) automatically assigns you an IP address. In this case the address is not permanent and each new connection a new address assigned to you. Why? For two reasons:Due to securityKnowing that the IP address is used by hackers (those big bad bearded, you know, right?) To infiltrate other computers, if someone finds your IP address by chance on the Net, it will not you persecute to life, because your address changes each connection and it will be impossible for him to find you every time.Availability AddressIP addresses are still a limit and can not be attributed to infinity as the maximum figure is 255,255,255,255.

Here's how it unfolds this step in detail, when searching for a domain name such as www.yahoo.com:
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.
Here are some basic principles and explanations to better understand the Internet and mainly domain names.
We will examine more closely the following aspects:The IP addressEach computer and each domain name to its IP address. Let us examine more closely the workings of the IP addressDNS serversEach address has an IP address, how to link the domain name and IP address?

The IP address
A domain name is the address of a website on the Internet.Internet is a network of computers. In the world of computers each computer is identified by a number, called an IP address, just like us with our address or our phone number.
The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.
Types of IP
The IP address can bepermanent (fixed IP), typically for servers that "host" websitesor non-permanent (dynamic IP), (private)Dynamic IP:Generally, when you connect to the Internet, your povider (Internet provider) automatically assigns you an IP address. In this case the address is not permanent and each new connection a new address assigned to you. Why? For two reasons:Due to securityKnowing that the IP address is used by hackers (those big bad bearded, you know, right?) To infiltrate other computers, if someone finds your IP address by chance on the Net, it will not you persecute to life, because your address changes each connection and it will be impossible for him to find you every time.Availability AddressIP addresses are still a limit and can not be attributed to infinity as the maximum figure is 255,255,255,255. The organization responsible for assigning IP addresses is the IANA (Internet Assigned Numbers Authority), American Association which among other things, addressing delegates at the European RIPE (European IP Networks). However a change in the protocol is about to be investigated but until the powers are controlled.Fixed IP:A second possibility is that the IP address is permanent (fixed IP).The static IP has the advantage that it allows a server constantly connected to the network. Its disadvantages are the relative loss of anonymity and be the easier prey of pirates (hackers). The fixed IP, today often pay, will tend to develop.
Thus, you have a permanent IP address or not, it lets you communicate on the Internet and identifies you on this one. And to prove that we are at your Current passing through here, here is your IP address:!

We will examine more closely the following aspects:The IP addressEach computer and each domain name to its IP address. Let us examine more closely the workings of the IP addressDNS serversEach address has an IP address, how to link the domain name and IP address?

The IP address
A domain name is the address of a website on the Internet.Internet is a network of computers. In the world of computers each computer is identified by a number, called an IP address, just like us with our address or our phone number.
The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.
Types of IP
The IP address can bepermanent (fixed IP), typically for servers that "host" websitesor non-permanent (dynamic IP), (private)Dynamic IP:Generally, when you connect to the Internet, your povider (Internet provider) automatically assigns you an IP address. In this case the address is not permanent and each new connection a new address assigned to you. Why? For two reasons:Due to securityKnowing that the IP address is used by hackers (those big bad bearded, you know, right?) To infiltrate other computers, if someone finds your IP address by chance on the Net, it will not you persecute to life, because your address changes each connection and it will be impossible for him to find you every time.Availability AddressIP addresses are still a limit and can not be attributed to infinity as the maximum figure is 255,255,255,255. The organization responsible for assigning IP addresses is the IANA (Internet Assigned Numbers Authority), American Association which among other things, addressing delegates at the European RIPE (European IP Networks). However a change in the protocol is about to be investigated but until the powers are controlled.Fixed IP:A second possibility is that the IP address is permanent (fixed IP).The static IP has the advantage that it allows a server constantly connected to the network. Its disadvantages are the relative loss of anonymity and be the easier prey of pirates (hackers). The fixed IP, today often pay, will tend to develop.
Thus, you have a permanent IP address or not, it lets you communicate on the Internet and identifies you on this one. And to prove that we are at your Current passing through here, here is your IP address:!
DNS servers
DNS = Domain Name Server = server domain name
We have seen that computers work with numbers (IP addresses).However, when you visit a site you insert its address (URL) and not its IP address. How the bond, then, is it done?
These are the DNS servers (Web address directory which was introduced in the late eighties) who are responsible for the correspondence between a domain name (virtual address) and IP address (physical address) .
The organization responsible for managing the DNS is the IANA (Internet Assigned Numbers Authority).

The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.
Types of IP
The IP address can bepermanent (fixed IP), typically for servers that "host" websitesor non-permanent (dynamic IP), (private)Dynamic IP:Generally, when you connect to the Internet, your povider (Internet provider) automatically assigns you an IP address. In this case the address is not permanent and each new connection a new address assigned to you. Why? For two reasons:Due to securityKnowing that the IP address is used by hackers (those big bad bearded, you know, right?) To infiltrate other computers, if someone finds your IP address by chance on the Net, it will not you persecute to life, because your address changes each connection and it will be impossible for him to find you every time.Availability AddressIP addresses are still a limit and can not be attributed to infinity as the maximum figure is 255,255,255,255. The organization responsible for assigning IP addresses is the IANA (Internet Assigned Numbers Authority), American Association which among other things, addressing delegates at the European RIPE (European IP Networks). However a change in the protocol is about to be investigated but until the powers are controlled.Fixed IP:A second possibility is that the IP address is permanent (fixed IP).The static IP has the advantage that it allows a server constantly connected to the network. Its disadvantages are the relative loss of anonymity and be the easier prey of pirates (hackers). The fixed IP, today often pay, will tend to develop.
Thus, you have a permanent IP address or not, it lets you communicate on the Internet and identifies you on this one. And to prove that we are at your Current passing through here, here is your IP address:!
DNS servers
DNS = Domain Name Server = server domain name
We have seen that computers work with numbers (IP addresses).However, when you visit a site you insert its address (URL) and not its IP address. How the bond, then, is it done?
These are the DNS servers (Web address directory which was introduced in the late eighties) who are responsible for the correspondence between a domain name (virtual address) and IP address (physical address) .
The organization responsible for managing the DNS is the IANA (Internet Assigned Numbers Authority).
Here's how it unfolds this step in detail, when searching for a domain name such as www.yahoo.com:
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.
Here are some basic principles and explanations to better understand the Internet and mainly domain names.

DNS servers
DNS = Domain Name Server = server domain name
We have seen that computers work with numbers (IP addresses).However, when you visit a site you insert its address (URL) and not its IP address. How the bond, then, is it done?
These are the DNS servers (Web address directory which was introduced in the late eighties) who are responsible for the correspondence between a domain name (virtual address) and IP address (physical address) .
The organization responsible for managing the DNS is the IANA (Internet Assigned Numbers Authority).
Here's how it unfolds this step in detail, when searching for a domain name such as www.yahoo.com:
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.
Here are some basic principles and explanations to better understand the Internet and mainly domain names.
We will examine more closely the following aspects:The IP addressEach computer and each domain name to its IP address. Let us examine more closely the workings of the IP addressDNS serversEach address has an IP address, how to link the domain name and IP address?

The IP address
A domain name is the address of a website on the Internet.Internet is a network of computers. In the world of computers each computer is identified by a number, called an IP address, just like us with our address or our phone number.
The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.

DNS servers
DNS = Domain Name Server = server domain name
We have seen that computers work with numbers (IP addresses).However, when you visit a site you insert its address (URL) and not its IP address. How the bond, then, is it done?
These are the DNS servers (Web address directory which was introduced in the late eighties) who are responsible for the correspondence between a domain name (virtual address) and IP address (physical address) .
The organization responsible for managing the DNS is the IANA (Internet Assigned Numbers Authority).
Here's how it unfolds this step in detail, when searching for a domain name such as www.yahoo.com:
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.
Here are some basic principles and explanations to better understand the Internet and mainly domain names.
We will examine more closely the following aspects:The IP addressEach computer and each domain name to its IP address. Let us examine more closely the workings of the IP addressDNS serversEach address has an IP address, how to link the domain name and IP address?

The IP address
A domain name is the address of a website on the Internet.Internet is a network of computers. In the world of computers each computer is identified by a number, called an IP address, just like us with our address or our phone number.
The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.
Types of IP
The IP address can bepermanent (fixed IP), typically for servers that "host" websitesor non-permanent (dynamic IP), (private)Dynamic IP:Generally, when you connect to the Internet, your povider (Internet provider) automatically assigns you an IP address. In this case the address is not permanent and each new connection a new address assigned to you. Why? For two reasons:Due to securityKnowing that the IP address is used by hackers (those big bad bearded, you know, right?) To infiltrate other computers, if someone finds your IP address by chance on the Net, it will not you persecute to life, because your address changes each connection and it will be impossible for him to find you every time.Availability AddressIP addresses are still a limit and can not be attributed to infinity as the maximum figure is 255,255,255,255.

Here's how it unfolds this step in detail, when searching for a domain name such as www.yahoo.com:
Search the DNS server that manages the domain name soughtThe browser first requests to DNS servers in the system which server handles extensions. Com.After obtaining the response, the browser asks the server which DNS server takes care of www.yahoo.com.After receiving the response, the browser finally asks the DNS server that manages www.yahoo.com, which handles www.yahoo.com, the latter responding that it is himself.The browser found the DNS server that manages the domain name www.yahoo.comObtaining the IP address of the website soughtThe browser asks the DNS server managing the site www.yahoo.com what is the IP address of the latter.The DNS server responds by giving the IP address of the site consists of 4 integersThe browser to find the physical address www.yahoo.com, it can now connect.
Here are some basic principles and explanations to better understand the Internet and mainly domain names.
We will examine more closely the following aspects:The IP addressEach computer and each domain name to its IP address. Let us examine more closely the workings of the IP addressDNS serversEach address has an IP address, how to link the domain name and IP address?

The IP address
A domain name is the address of a website on the Internet.Internet is a network of computers. In the world of computers each computer is identified by a number, called an IP address, just like us with our address or our phone number.
The IP address is then used to identify uniquely each computer connected to the Internet (according to the Internet communication protocol, Internet Protocol). It consists of four numbers between 0 and 255 separated by dots (eg 194.252.170.90).
But what are these numbers? The address of our example, decomposed:195,252. this is the address of a network,170. is the address of a network,90 is the address itself.Websites (html, java, images ...) are located on servers (dedicated computers responsible for storing, among other things, the Web pages and files). These can handle multiple IP addresses, and each site "hosted" on the server to its own IP address.
Types of IP
The IP address can bepermanent (fixed IP), typically for servers that "host" websitesor non-permanent (dynamic IP), (private)Dynamic IP:Generally, when you connect to the Internet, your povider (Internet provider) automatically assigns you an IP address. In this case the address is not permanent and each new connection a new address assigned to you. Why? For two reasons:Due to securityKnowing that the IP address is used by hackers (those big bad bearded, you know, right?) To infiltrate other computers, if someone finds your IP address by chance on the Net, it will not you persecute to life, because your address changes each connection and it will be impossible for him to find you every time.Availability AddressIP addresses are still a limit and can not be attributed to infinity as the maximum figure is 255,255,255,255. The organization responsible for assigning IP addresses is the IANA (Internet Assigned Numbers Authority), American Association which among other things, addressing delegates at the European RIPE (European IP Networks). However a change in the protocol is about to be investigated but until the powers are controlled.Fixed IP:A second possibility is that the IP address is permanent (fixed IP).The static IP has the advantage that it allows a server constantly connected to the network. Its disadvantages are the relative loss of anonymity and be the easier prey of pirates (hackers). The fixed IP, today often pay, will tend to develop.
Thus, you have a permanent IP address or not, it lets you communicate on the Internet and identifies you on this one. And to prove that we are at your Current passing through here, here is your IP address:!
DNS servers
DNS = Domain Name Server = server domain name
We have seen that computers work with numbers (IP addresses).However, when you visit a site you insert its address (URL) and not its IP address. How the bond, then, is it done?
