My IP only changes if there has been a power outage for a long period of time, which I suppose resets the modem or something. We use RoadRunner if that tells anyone anything. I put my entire IP on RC, only had to have it fixed maybe twice if that the whole time I was manager, I believe MG did also, I had to change his last number a couple of times. I dont exactly know what you mean by "outside IP" I get my IP by right clicking on the connection icon on the taskbar (WinXP).

Okay, how is your network setup? Do you have one cable modem that is shared between your computers or do you have two separate cable modems? What Houdiniman means is that in a home network setup using one cable modem, the home network uses local IP addresses. Each one of your machines can have ANY IP you choose (though most people just use the standard 192.168.1.* setup for ease of configuration). When you access the internet through a home network, the node that requests internet access forwards the request to a router. The router receives the request and sends it to your cable modem which then fetches the content and sends it back to the router which then sends it back to you. In this setup, the router is known as a gateway because all internet access requests must first go through the router before going to the cable modem. The reason you do this is because cable modems are assigned an IP by your ISP (it could be static or dynamic, but it usually static). Since the modem is only assigned one IP, only one computer can use it at a time because two computers cannot share the same IP address. The router allieviates this problem by serving as a gateway to the cable modem. So the router is the only node assigned an internet IP. Keeping that in mind, all local computers will have the same internet IP since the router is the only node that is assigned one. If you have two cable modems, then each computer will have its own internet IP since each cable modem is assigned its own.
