If you have ONE internet line in, but THREE PCs in your house, does each PC have

[steven d]

a different IP address? I have ONE line in, but three different PCs connected through a router in one room. Does each PC have a diiferent IP address, or they the same?

Also, how do I find out what my IP address is?

If they are connected to a Wireless or Wired router yes they will all have a different IP who normally starts with 192.68

Check open network connection and click on your wired or wireless adapter and on the left inside of XP you will see the details of the connection : submask , IP address etc..
