Internet Protocol

Internet Protocol (IP) is a method by which data is sent from one computer to another on the Internet. Each computer on the Internet (which is known as host) has at least one IP address that uniquely identifies it with all other computers on the Internet.

When you send or receive data (for example, an e-mail note or a web page), the message gets split into smaller chunks called packets. Each of these packets includes both the sender's internet address and receiver's address. Any packet is sent to the first gateway computer, which understands a small portion of the Internet. The gateway computer reads the destination address and forwards the packet to a nearby entrance, which, in turn, reads the destination address and the Internet before it is read as long as a gateway packet is used as a neighborhood or a computer's domain. Does not recognize The gateway then sends the packet directly to the computer whose address is specified.

Because a message is divided into several packets, each packet, if necessary, can be sent through a different route on the Internet. Packets can come in a different order than the order sent to them. Internet Protocol only saves them. It is up to another protocol, the Transmission Control Protocol (TCP) to bring them back in the correct order.

The IP is a connection-less protocol, which means that there is no continuous connection between the last point of communication. Each packet that travels through the internet, is not considered to have any connection with any other entity of data as an independent entity of data. (The reason for putting packets in correct order is TCP, connection-oriented protocol that tracks the packet sequence in the message.) In Open Systems Interconnection (OSI) communication model, IP is in Layer 3, Networking layer

Today the most widely used version of the IP is Internet Protocol version 4 (IPv4). However, IP version 6 (IPv6) is also supported. IPv6 provides for too many addresses and therefore for the possibility of many more internet users. IPv6 includes capabilities of IPv4 and any server that can support IPv6 packets can also support IPv4 packets.
