IP is the abbreviation of Internet Protocol, which is the network layer protocol in TCP/IP system. The purpose of designing IP is to improve the scalability of the network: first, to solve the internet problem and realize the interconnection of large-scale and heterogeneous networks; The second is to divide the coupling relationship between the top-level network application and the bottom-level network technology, so as to facilitate their independent development. According to the end-to-end design principle, IP only provides connectionless, unreliable and best-effort packet transmission services for the host.
