Looking up the IP address of a computer

[id : 328] [11/03/2009] [hits : 33509]


Each computer that is connected to the network and Internet has a unique address, the IP address.

An IP address consists of 4 numbers varying between 0 and 255, each number separated by a. (dot).

Some examples:

To find out the IP address of your computer, can you use the following webpage:


This page also indicates if your IP address is registered with the networkteam (this SHOULD be the case).
