For a host of useful network information, open up your DOS command prompt, either by Start-->Run-->cmd or Start-->Accessories-->Command Prompt, and enter in 'ipcomfig.' It'll have your IP address, your subnet mask, your ISP's DNS suffix, and default gateway.
This is especially important given that sometimes Windows' built-in network tools display innaccurate information about your IP address. Although I just tried Phazon's method and it matches my ipconfig.

thanks to all three of you i figured it out
