Internet Protocol

IP itself works at the network layer of the OSI reference model. It is responsible
for tracking the addresses of devices on the network, determining how IP
datagrams are to be delivered, and sending IP packets from one host to
another across a specific segment. In essence, IP provides a virtual representation
of the network that is independent of any of the individual network segments,
acting more like a national delivery service than a local courier service.
