Internet Protocol (IP) is the predominant set (or communications protocol) of virtual message Formats and policies for replacing messages between Computer Systems across a unmarried commUnity or a chain of Interconnected Networks, the usage of the Internet Protocol Suite (frequently known as TCP/IP). Messages are excHanged as Datagrams, also called Records Packets or simply packets.
IP is the number one protocol in the Internet Layer of the Internet Protocol Suite, which is a set of communications protocols together with 4 Abstraction layers: link layer (lowest), Internet layer, shipPing layer and Application Layer (highest).
The essential cause and venture of IP is the delivery of Datagrams from the source Host (supply Laptop) to the vacation spot host (receiving Computer) based totally on their addresses. To reap this, IP consists of techniques and sySTEMs for putting tags (cope with statistics, which is a part of Metadata) within datagrams.
The system of setting those tags on datagrams is known as Encapsulation.
Think of an anology with the postal Device. IP is just like the U.S. Postal System in that it permits a Package deal (a datagram) to be addressed (encapsulation) and positioned into the device (the Internet) via the sender (source host). However, there may be no direct link among sender and Receiver.
The bundle (datagram) is nearly always divided into portions, however every piece consists of the address of the receiver (destination host). Eventually, every piece arrives on the receiver, frequently by using special routes and at extraordinary Instances. These routes and times are also determined by means of the Postal System, that is the IP.
However, the Postal System (inside the transport and application layers) places all of the portions back together before delivery to the receiver (vacation spot host).
Note: IP is truly a Connectionless Protocol, meaning that the Circuit to the receiver (destination host) does no longer want be set up earlier than transmission (via the supply host). Continuing the Analogy, there does now not want to be a Direct Connection among the physical go back deal with on the letter/package deal and the recipient cope with earlier than the letter/package is sent.
Originally, IP was a connectionless datagram Carrier in a transmission manage Software created through Vint Cerf and Bob Kahn in 1974. When format and policies had been applied to permit connections, the Relationship-orientated Transmission Control Protocol became created. The two collectively form the Internet Protocol Suite, regularly called TCP/IP.
Internet Protocol version four (IPv4) became the first major Model of IP. This is the dominant protocol of the Internet. However, iPv6 is lively and in use, and its Deployment is growing everywhere in the global.
Addressing and Routing are the most complex factors of IP. However, intelligence in the commuNity is placed at Nodes (network interconnection points) in the form of Routers which Forward datagrams to the subsequent acknowledged Gateway at the route to the Final destination. The routers use Interior Gateway Protocols (IGPs) or external gateway protocols (EGPs) to assist with making forwarding route decisions.
Routes are decided by means of the routing prefix inside the datagrams. The routing Procedure can therefore become complex. But at the Velocity of mild (or almost so) the routing intelligence determines the fine route, and the datagram pieces and datagram all sooner or later arrive at their vacation spot.

When we refer to IP as an acronym of Internet Protocol, we mean that IP is formed by taking the initial letters of each significant word in Internet Protocol. This process condenses the original phrase into a shorter, more manageable form while retaining its essential meaning. According to this definition, IP stands for Internet Protocol.
