The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.
What is TCP?
TCP maintain a network conversation via which application programs can exchange data. TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other. Together, TCP and IP are the basic rules defining the Internet.
What is the purpose of IP?
IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers
Version of IP in History
In May 1974, the Institute of Electrical and Electronic Engineers (IEEE) published a paper entitled "A Protocol for Packet Network Intercommunication". The successor to IPv4 is IPv6. Its most prominent modification from version 4 is the addressing system. IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses. IP versions 0 to 3 were experimental versions, used between 1977 and 1979.
Who invented IP?
Robert E. Kahn
He is an American electrical engineer, who, along with Vint Cerf, invented the Transmission Control Protocol and the Internet Protocol, the fundamental communication protocols at the heart of the Internet.
