When a multiplayer game is played over the Internet, the joining players must know the host's IP address in order to be able to join the game. The host can find out his current IP address (on most machines the address changes whenever a player connects to the Internet or at regular intervals, when using a cable modem) by running Windows IP Configuration utility:
