IP address

An IP address (Internet Protocol address) is a unique number that devices use in order to identify and communicate with each other on a network. Any participating device &mdash; including routers, computers, time-servers, etc. &mdash; must have its own unique address. This allows information passed onwards on behalf of the sender to indicate where to send it next, and for the receiver of the information to know that it is the intended destination. The numbers currently used in IP addresses range from 0.0.0.0 to 255.255.255.255.
