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) .

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

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

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).
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

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. 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:!

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

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

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.

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?
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).

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

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. The organization responsible for assigning IP addresses is the

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 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?
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
