Same IP on two Computers?! 1

[fatbob51]

Hi!
First of all I wonder if its even possible to have two WORKING(Internet and all runs great)computers with the same IP.
and 2:nd how do I get to know an IP on a computer thats connected to a LAN (which means it has a "LAN IP"), and when I use the "normal" ipconfig thing in a cmd I only get the LAN IP.
And once I try to enter a site that shows my IP it gives me the same IP as another computer thats connected to the same network.
Is there anyway to find out which IP the computer "really" has,or?

Your router is doing Network Address Translation (NAT). This allows you to "share" one public IP (supplied by your ISP) between many computers on your private LAN.

When you make a connection to an internet site, your router processes your request, changes your private IP address to the public address assigned by your ISP and forwards. As the site responds, the router sorts out which data belongs to which computer and forwards it along. Simplified view of things, but should do for now.

The IP reported by ipconfig is your private IP used on your LAN, the IP reported by a website is your public IP assigned by your ISP.
