Today, I will talk to you about the characteristics of ipv6, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

The characteristics of ipv6 are as follows: 1, the length of PV6 address is 128bits, and the address space is increased by 2 times 96 times; 2, flexible IP header format; 3, IPV6 simplifies the header format; 4, improve security; 5, support more types of services; 6, allow protocols 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-.

Characteristics

(1) the length of the IPV6 address is 128bits, and the address space is increased by 2 to the power of 96.

(2) flexible IP header format. The variable-length option fields in IPV4 are replaced with a series of fixed-format extension headers. The appearance of the option part of the IPV6 has also changed, so that the router can simply pass the option without doing any processing, speeding up the packet processing speed.

(3) IPV6 simplifies the header format of the message, with only 7 fields, which speeds up message forwarding and improves throughput.

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

(5) support more service types; add support for automatic configuration. This is an improvement and extension of the DHCP protocol, which makes the management of the network (especially the local area network) more convenient and fast.

(6) allow the protocol to continue to evolve and add new functions to adapt it to the development of future technology.

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 free, especially for Education Network users, it is completely free. Because access to the education network is free, but access to the external network will be charged, but the charge is limited to ipv4, the current pilot phase of ipv6 is completely free.

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

At present, most of them are mixed networks of ipv4 and ipv6, and ordinary users need to be configured to use ipv6. In addition, ordinary home routing does not support ipv6, and users who use routers are out of touch with ipv6.

After reading the above, do you have any further understanding of the characteristics of ipv6? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
