How Can I View My High Speed Cable Modem IP Address?
An Internet Protocol (IP) address is a 32-bit numerical label assigned either statically or dynamically to a computer network, for example, 192.77.178.162 is an IP address. A cable modem is used to provide broadband Internet access to computer networks in the form of cable Internet. A cable modem has two types of IP addresses, a customer side IP address and an ISP (Internet Service Provider) side IP address. These addresses can be viewed using a computer connected to the cable modem with an active Internet connection.
