Internet protocol

[¦in·tər‚net ′prōd·ə‚kȯl]
The set of standards responsible for ensuring that data packets transmitted over the Internet are routed to their intended destinations. Abbreviated IP.

Internet Protocol

(IP) The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. It provides packet routing, fragmentation and re-assembly through the data link layer.

IPv4 is the version in widespread use and IPv6 is just beginning to come into use in 2000.

Internet Protocol

The communications protocol of the public Internet, many wide area networks (WANs) and most local area networks (LANs). The Internet Protocol (IP) is part of the TCP/IP protocol suite, and the terms "IP network" and "TCP/IP network" are synonymous.

Packet Switching
IP uses a packet-switched architecture, in which data are broken up into smaller "packets," with each packet containing a source address and destination address. IP packets are handed over to a data link layer protocol, such as Ethernet, for the actual, physical transmission to the next node in the network path.

IP is the Network Layer
While "IP" refers to the entire TCP/IP protocol suite, the term "IP layer" refers to just the network-to-network part, occupying layer 3 in the "protocol stack" (see below). To learn about IP networking, see OSI model, TCP/IP, TCP/IP abc's, IP address and IP on Everything.

The TCP/IP "Stack"
The layer 3 Internet Protocol resides in the middle of the TCP/IP stack. It accepts packets from the upper layer TCP or UDP protocols and hands them to a lower layer data link protocol. Within a local network, the data link protocol is typically Ethernet. Within the public Internet, the data link protocols are SONET, ATM, frame relay and Carrier Ethernet.
