What is an Internet Protocol Address?

An Internet Protocol Address, or IP Address, is a unique number consisting of 4 parts separated by dots, like 216.239.51.100

Every machine on the Internet has a unique IP address - if a machine does not have an IP address, it cannot be called up by any other machine on the Internet,

The IP Address is like a telephone number...it is the number that other computers use to "call" your computer. For example, whether you enter 216.239.51.100 in your web browser or www.google.com, both addresses are the same. The only difference is, one uses the IP address and the other uses the domain name address.
