I'm not sure what you are trying to accomplish. The machine I'm typing
this on has a 192.168.x.x number. The router that gave it to me also
has a 192.168.x.x number. However, I know that that is not the IP that
the world sees when my packets finally leave the building.

What if your machine has multiple interface cards in it?

What are you trying to accomplish?
