If you don't know what your IP address is, try this:

You can also do winipcfg for 9x machines, and ipconfig for NT/2k/XP machines. I believe that ipconfig is run from a command window, so make sure to open a command line before running it, or you won't see what the results are.
To run, click on Start/Run, and type in the program for your OS.
