Comparative Research on Key Technologies from IPv4, IPv6 to IPV9

Since the United States developed the IPv4 protocol based on TCP/IP in the 1970s, it has been more than 30 years old. IPv4 is the “fourth edition of the Internet Protocol.” From a technical point of view, although IPv4 has a brilliant performance in the past, it seems to have revealed many drawbacks. With the addition of multimedia data streams and security considerations, IPv4’s address space is running out of crisis, and IPv4 is no longer sufficient. Under such circumstances, IPv6 was born as needed. When designing IPv6, not only the IPv4 address space was expanded, but also the parties to the original IPv4 protocol were reconsidered and a lot of improvements were made. In addition to the large number of addresses, there is higher security, better manageability, and better support for QoS and multicast technologies. It is an abbreviation for “6th Edition of Internet Protocol.” IPV9 was proposed in 1992 to replace the IPv4 with the ISO/OSI CLNP protocol, using the 20B NSAP address and the platform for the available OSI transport protocol. Later, DDNS was introduced and gradually developed into an IPV9 decimal network with a 256-bit address. IPV9 masters “the right to control the use of the Internet, the allocation of IP addresses, the initiative of information monitoring, the right to use routing protocols, and the ownership of technology patents.” Therefore, the research and application of a new generation of Internet Protocol Next Generation has become a worldwide hotspot.
