pitbos, you can tell if it's a local or external address by the numbers. I don't know much more than that about it. I read somewhere that numbers within a certain range are reserved for local addresses and other numbers are reserved for external addresses. Use Google, or better yet the wikipedia, to find out more.

IPs beginning with 192.168.x.x and 10.0.x.x are local. All others are external.

If you're interested in more detail the following article put out by 3COM is very good reading:
