An IP (Internet Protocol) is the standard way of sending collected packets of information (or datagrams) across the internet.
A unique IP address is assigned to each server and each device connected to the internet. These can be permanent (static) or temporary (dynamic). They are expressed as a series of numbers that identify senders and receivers of data across a network. The number represents the domain, the network, the subnetwork and the host computer.
IP addresses have many uses. For example, cookies are assigned using IP addresses so websites can recognise individual users and serve them tailored content.
