What are the characteristics of ipv6

Features of ipv6: 1. The PV6 address length is 128 bits, and the address space is increased by 2 to the 96th power; 2. Flexible IP message header format; 3. IPV6 simplifies the message header 4. Improve security; 5. Support more service types; 6. Allow the protocol to continue to evolve.

IPv6 is the abbreviation of "Internet Protocol Version 6". It is the next generation IP protocol designed by IETF to replace the current version of IP protocol-IPv4-.

Features

(1) The IPV6 address length is 128 bits, and the address space is increased by 2 to the 96th power;

(2) Flexible IP packet header format. The variable-length options field in IPv4 is replaced with a series of fixed-format extension headers. The appearance of the option part in IPv6 has also changed, allowing the router to simply pass the option without doing any processing, speeding up packet processing.

(3) IPV6 simplifies the message header format, with only 7 fields, speeding up message forwarding and improving throughput;

(4) Improves security. Identity authentication and privacy are key features of IPV6.

(5) Support more service types; added support for automatic configuration. This is an improvement and extension to the DHCP protocol, making the management of the network (especially the LAN) more convenient and faster.

(6) Allow the protocol to continue to evolve, add new features, and adapt it to future technology developments.

These characteristics can also be said to be the advantages of ipv6 over ipv4

In addition to the above advantages, the current ipv6 has another important advantage, that is, it is free, especially for education networks For users, it is completely free. Because access to the education network is free, but access to the external network is charged, but the charge is only limited to IPv4. The current experimental IPv6 is completely free.

Another point is that there is no GFW on ipv6, you can see the whole picture of the Internet

At present, it is basically a mixed network of ipv4 and ipv6, and ordinary users need to configure it to use ipv6. In addition, ordinary home routers do not support ipv6, and users who use routers have no chance of ipv6.
