IP Address.

When I goto WhatIsMyIP my IP address comes up to be 66.xxx.xxx.xx
But when I do ipconfig in CMD Prompt my IP comes up to be 192.xxx.xx.xx

I do have a router that my computer connects to.

Why are the IP address's different?

Also I wanted to know if the the router works, because before I reinstalled Windows and used BitTorrent to download I always had a NAT Eerror. Now it doesn't give me that error. I can't access the router settings, because the guy who installed the wireless internet for our motel wont tell me the password to the router(Yes I tried "admin").:angry::angry::angry::frusty:

The 192.168.x.x is you local network IP address and has been created by your router. The local one isn't seen outside your local network.

The 66.x.x.x is a wide area network (WAN) IP is the one your modem uses to connect to your ISP.

Your router works if you can communicate.
