You can use the PING utility included with Windows to determine the “real” IP address of a web site. Before using this utility, make sure you are not mapping a host name to some IP address with HostName Commander, because if you do, the PING utility will show the address you’ve set up with HostName Commander, instead of the “real” IP address.
To run the PING utility, click on the Windows Start button, and choose Run from the Start Menu. If you use Windows 95,98, or Me, enter “command” (without the quotes) as the command line to run. If you use Windows XP,2000, or NT, enter “cmd” (again, without the quotes). Click OK and the command prompt window should appear on the screen.

Now enter the word “ping” (without the quotes) followed by a space, followed by the host name you want to determine the IP address of, and press Enter:
(Keep in mind that the IP address may change in the future!). If the PING utility reports an error, make sure your computer is connected to the Internet when you are running it
