Review Your Network Connections Working with a Router The Cable modem is a router. Its primary function is to provide an interface between the Internet and your Local Area Internet. Every computer or server on the Internet needs an Internet Protocol address. The IP address must be unique, like a phone number, so that information packets can find the right destination. Your Cable router will be assigned a unique IP address by the ISP. In turn, your Cable router will direct Internet traffic to all of the computers in your office or home. The Cable router will also assign default IP addresses to the computers in your LAN. The addresses will be similar to the one on my machine: 192.168.2.101 CAT5 (category 5) network cable is similar to a phone cord. It's just a little bigger. The cable is RJ-45, and the phone cord is RJ-11.   When the phone cord is plugged in right, the phone rings. The network cable works the same way.
