The internet setup at my home is as follows:
I have a cable modem (192.168.100.1) connected with a coaxial cable. The cable modem is connected to a wireless router (192.168.1.1) via an ethernet cable. I'm using internet on my laptop by connecting to the wireless network.
Entering the aforementioned IP addresses I can access both the cable modem and the router. Everything seemed fine but when I accessed the cable modem page (192.168.100.1) I noticed that there was a field there that said "IP Address: 10.199.0.77". When I enter this address in my browser I see the same page as 192.168.100.1. "10.199.0.77" is NOT my WAN IP address, which is x.x.34.56.
Why does my cable modem have multiple local IP addresses?
