Internet Protocol version 4
From Network Dictionary Wiki
(Redirected from IPv4)
Internet Protocol version 4 (IPv4), defined in the RFC 791, is the most widely deployed networking technology. When people talk about IP, most likely it refers to the IPv4. IPv6 is the new version of Internet Protocol (IP) based on IPv4. The Internet Protocol (IP) is a network-layer (Layer 3) protocol in the OSI model that contains addressing information and some control information to enable packets being routed in network. IP is the primary network-layer protocol in the TCP/IP protocol suite. Along with the Transmission Control Protocol (TCP), IP represents the heart of the Internet protocols.
