Can I check my computers IP Address ??

[GameBreaker]

Is there a way for me to check what my computers IP address is. I have multiple computers running off of the same Router and would like to see the addresses for each individual computer.

Basically the cable goes from the wall to a modem and then to a wireless router and then to 3 computers. All 3 computers are hooked to the router thru wires even though I could use the wireless with my laptop.

I want to make sure all three computers have seperate individual IP addresses.

Thanks.
