IP Address

An IP Address, or Internet Protocol Address, is a unique, numerical address that is assigned to each device on a network that is connected to the Internet.  Domain names are mapped to a specific IP Address, which then tells the location of that web site on the Internet. An example of an IP address is 209.85.171.99, which is one of many Google IP Addresses.  The hard to remember string of numbers was the reason why domain names were created in the first place.
