Find Your IP Address

Written by Mark Sanborn: Aug 26, 2007

Since most of the computers today communicate via the TCP/IP Protocol (don’t worry if you don’t know what that is) these computers must have an IP address in order to communicate. You can think of the IP address like a phone number or street address. For example, if we wanted to talk to http://www.google.com we must dial up their number (IP address) and ask them for something. Maybe we want to ask them if we can do a search on socks. When Google receives this request it may respond by sending a package to our computer. It does this by sending the package (list of websites that have information about socks) to our computer’s IP address. If we didn’t have an IP address Google wouldn’t know how to deliver the package.

The IP address is the basic way computer communicate on modern networks so it is sometimes very useful to know your IP address for many reasons. Chances are if you are reading this you already have a reason to know your IP address so I will show you how to find yours now.
