IPV6 APPLICATION PROSPECTS, WHAT IS IPV6 TECHNOLOGY?

Of course, there are more IPs available, and it is convenient to surf the Internet.

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

Features of IPv6 technology:

The IPv6 address length is 128 bits, and the address space is increased by 2 to the 96th power.

Flexible IP packet header format. The variable-length option fields in IPv4 are replaced with a series of fixed-format extension headers. In IPv6, the options section also appears in a different way, so that routers can simply pass through the options without doing any processing, speeding up packet processing.

IPv6 simplifies the packet header format with only seven fields, speeding up packets** and improving throughput.

Improve security. Authentication and privacy are key features of IPv6;

Support for more service types; Added support for auto-provisioning. This is an improvement and expansion of the DHCP protocol, which makes the management of networks (especially local area networks) more convenient and faster;

Allows the protocol to continue to evolve, adding new features and adapting it to future technological developments.

These features can also be said to be the advantages of IPv6 over IPv4.

In addition to the above advantages, the current IPv6 also has another important advantage, that is, it is free, especially for the users of the education network, 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, and IPv6 in the current trial stage is completely free.

IPv6 is what benefits people can bring to people.

The application of IPv6 in China is described as follows:

1. China has always attached great importance to the construction and development of IPv6, and since the promulgation of the Action Plan for Promoting the Large-scale Deployment of Internet Protocol Version 6 (IPv6) in 2017, a number of policies and regulations related to IPv6 have been formulated, pointing out the development direction and clarifying the stage goals for the large-scale deployment of IPv6.

This year is an important period for IPv6 deployment, and it is the first year of the 14th Five-Year Plan to build a digital China. Next, the three parties will give a brief introduction to the IPv6 deployment in 2021 from the aspects of active users, bandwidth users, terminal readiness, network readiness, and ** applications.

3. Since the issuance of the Action Plan for Promoting the Large-scale Deployment of Internet Protocol Version 6 (IPv6), IPv6 Internet active users have maintained rapid growth, and by the end of 2021, the number of IPv6 Internet active users in the country has reached 100 million, accounting for the total number of Internet users in the country.

4. The number of active IPv6 terminal connections refers to the number of fixed and mobile terminals that have obtained IPv6 addresses and have valid IPv6 traffic records (excluding ping and domain name resolution traffic) within 30 days, which can reflect the IPv6 support of China's basic network. At present, the scale of fixed and mobile terminals in China exceeds 1.5 billion, ranking first in the world.
