Hey Jim: Basically, how it works is that you probably have a DHCP address. If you're behind a router, what usually happens is that the address your machine is getting is different than the address that it's sending out. For instance, if you're on a cable modem service, the ISP assigns an IP to your cable modem. This would be a global IP address that the world can see you at. If you have a router connected to this, it uses NAT to assign an IP address locally to all the machines on your network.
In order to host a server behind a routed home network, you need to get the external interface address of your border router, and then have your border router forward incoming ports to a specific host inside your network. ~Scott Jim Sager wrote: > How can you tell the difference between a real IP and a home network? > > I'm starting to write some S2P2P(server to peer to peer) software, and > I need to be able to differentiate between a real IP and a home > network IP.
