What is ITIcomputers.com IP address finder?
ITIcomputers.com IPaddress finder is a web site that automatically
detects and displays your computer's IP address. This can be helpful
for configuring a computer on a network, setting up communications
software, or troubleshooting an Internet connection. Your Internet
Service Provider or IT help desk may ask you to visit this site
when you're having problems with your Internet connection.
What is an IP address?
Just as telephones are identified by unique telephone numbers, computers
on the Internet are identified by unique series of numbers called
"IP addresses". Each IP address consists of four numbers separated
by three periods; for example, "192.168.1.1". Whenever your computer
talks to another computer on the Internet -- such as when you visit
a web site -- the name of the other computer must be converted into
an IP address before communication can take place. (Incidentally,
"IP" stands for "Internet Protocol".)
Where do I get an IP address?
Most computers automatically get their IP addresses from the network;
that is, they are "dynamically assigned" by an Internet Service
Provider or IT department. The technologies that make this possible
are "DHCP" ("Dynamic Host Configuration Protocol") and "PPP" ("Point
to Point Protocol"). Fortunately, most modern operating systems
handle DHCP and PPP without much effort on the part of the user.
The only disadvantage of a dynamically-assigned IP address is that
it can change each time you connect to the Internet. (This can also
be viewed as an advantage, of course, as it makes it more difficult
for hackers to track you down.) If you are using software that requires
you to know your IP address, you may wish to visit myIPaddress.com
whenever you reconnect to the Internet.
If you have a continuous connection to the Internet, your Internet
Service Provider may assign you a "static IP address". A static
IP address identifies your computer on the Internet using the same
address as long as you remain with the same ISP. This is necessary
if your computer is to provide services on the Internet, such as
e-mail or web hosting.
My IP address is wrong! How can that be?
If your computer is located behind a firewall, the firewall may
be hiding your computer's actual IP address from myIPaddress.com.
In which case the IP address displayed is actually the IP address
of the firewall, not your computer.
Similarly, if your computer is behind a "proxy server" or "web
cache" (i.e., a computer that intercepts requests for web pages
in order to speed up frequently-requested pages), the IP address
displayed is probably the IP address of the proxy server or web
cache -- not your computer.
Note that your computer may be behind a proxy server or web cache
without your knowledge! A number of companies and Internet Service
Providers use "transparent web caches", which intercept requests
for web pages without any special configuration of your computer.
