Comparison Research on Future Network Between IPv4, IPv6 and IPV9

IPv4 is the most widely used protocol on the Internet, and its address space is 232. In the early stage of the Internet, due to the underestimation of the development of Internet, IP resources were very limited. By 2010, there was no address that could be allocated. In order to solve the problem of insufficient addresses, the IETF designed the next generation IPv6 protocol to replace IPv4, IPv6 has 2128 addresses in theory, and however, only one-eighth of the addresses can actually be allocated to end users. At present, 128 barcodes are already having 128 bits, and it cannot be covered, so IPv6 have some considerable limitations. In 1998, Chinese researcher proposed IPV9. In order to distinguish from IPv4 and IPv6, the V in IPV9 is uppercase, not lowercase. The IPV9 includes three technologies: a new address coding design, a new addressing mechanism and a new address architecture design. These technologies constitute the core technology system at the bottom of the new generation IP network. The new network framework designed on this basis can form a network system that is connected and compatible with existing networks. IPV9 is not a simple upgrade of IPv4 or IPv6 and its address space is 10256 by default. The massive address can meet the needs of human activities about 750 years, this paper will introduce the characteristics of the future network, and comparison the system between the IPv4, IPv6 and IPV9, and lay a solid foundation for the subsequent development.
