Internet Protocol Address

An Internet Protocol address (IP address) identifies a device connected to the Internet. There are two formats – the widely used version 4 (IPv4) and the newer version 6 (IPv6). Both are numerical labels which are used by network connection electronics to enable communication between devices, even though many devices are sharing the same cables and other communication links.
