That's how I typically check it dude.  Just so everyone knows, to open a command window hit START / RUN and enter "cmd".  For even more detailed info (including physical MAC address), at the DOS command prompt try:  ipconfig /all

For those not wanting to open a command window, you can always just go to the Control Panel, Network Connections, selection your local ethernet port (should be connected) and hit Status to get your IP address.

However, let's be clear that if you have a router, your machine IP address is probably not the same as your public IP address on the web.  If you are looking for your public IP address, you have to get that off the router or through a website such as the one listed above.  Finally, if your machine IP address is different from the one shown on the website, don't expect to give either address to a friend and have them connect to your machine for a game.  For that to work, you need to modify the port forwarding configuration in your router.  If you are trying to get a game working with a couple of computers in the same house or apartment, use your local machine addresses instead of the one from the webpage (as both computers in the house will show the same IP on the webpage anyway if they are on a standard shared network with a single internet connection).
