What is the IP address of my pc when it is connected through a router? Is it the default ip address assigned by the router? For example I am using a linksys. The router is setup as a dchp so it will assign the pc a ip address of 192.168.1.100 or something similar to that. Or is the ip address the one assigned from my service provider? If I want people to connect to my pc which ip address do I give them?
