Find IP's of NIC's on PC & Network? 1

[cjtaylor]

How would one go about finding the IP address of the NIC on your PC and across the network?

Thanks

Try this one, I got it off of a website, but I don't know whick one. There are 1 other methods of finding it if this one doesn't work. Just tell me if you need them. It might get a little confusing if I stick all three methods in.
