The main function of IP is to give interconnection of sub-networks to create an internet so it can transmit data. This IP protocol can give four main functions Basic data transfer addressing and routing as well as fragmentation of data-grams. The IP layer provide entry into the delivery system that is for transporting data toward the internet. commonly when we hear the term IP we think of networks that connected with each other through devices usually known as routers, which is used to connect more than sub-networks with each other. This is true but IP can give more than these tasks. IP can give connectionless data delivery among nodes on an IP network. The main reason for IP is to give a basic algorithm for transferring data to and from a network. It uses two functions in order to obtain these implements which are addressing and fragmentation. also for upper layer protocols IP can provide connectionless delivery. This mean that IP will not set up a session among the transmitting station and the receiving station before submitting the data to the receiving station. IP will not tell the sender or receiver of the situation of the packet. It solely tries to transfer the packet and will not make any faults that it is facing in this attempt.
