What is a Fixed IP address?

A fixed IP address is sometimes known as a static IP address. It is an address that is assigned to a computer by an Internet service provider (ISP) to be its permanent address on the Internet.

Computers use IP addresses to locate and talk to each other on the Internet, much the same way people use phone numbers to locate and talk to one another on the telephone. The machine will retain that IP address no matter how many times it connects/disconnects from a network.
