Global IPv4 address exhaustion IPv6 new system is forming

The reality that IPv4 addresses around the world are running out has been publicized for many years, and that day has finally arrived.In fact, as early as the 1980s, researchers have foreseen such a future, and ushered in the depletion of top-level IPv4 addresses in 2012. Today, the regional IPv4 address inventory is exhausted.

With the final / 22 IPv4 allocation of the European Network Information Center (RIPE NCC) from the available pool at UTC 1 15:35 on November 25, 2019, all 4.3 billion IPv4 addresses around the world have been assigned, meaning that no more IPv4 addresses can be assigned to (ISP), the Internet service provider, and other large network infrastructure providers.

As a protocol standard, Internet Protocol IP is the only identification of network equipment connected to the network, which is called the "house number" on the Internet. At present, there are two versions of IP protocol: IPv4 and IPv6. IPv6 can provide more address resources than IPv4.

The exhaustion of IPv4 address has been foreseen for a long time, and the new internet protocol system IPv6 is advancing steadily.

In the past 30 years, the United States has taken advantage of its first mover advantage to dominate the root server governance system. Within the IPv4 (Internet Protocol version 4) system, the world is limited to a total of 13 root servers, the only primary root is deployed in the United States, the remaining 12 secondary root servers are 9 in the United States, 2 in Europe and 1 in Japan - we are all Internet guests.

Due to the late start of the Internet in China, the total number of IPv4 addresses allocated and the per capita volume are relatively low, and the rapid development of the domestic Internet, the country has to use the network address conversion technology, which makes the domestic network structure complex, high delay, high equipment cost, to a certain extent, restricts the development of the domestic Internet.

As early as 2010, China has realized that there is no way out for China to deploy large-scale IPv6 network, so we must increase the strength of IPv6 address application to avoid the repeat of the situation of falling behind in the era of IPv4 network.

In order to break the root server dilemma, China led the initiative of Yeti DNS project, which recruited 25 root server operation volunteer units from all over the world to jointly test and verify IPv6 root server operation, domain name system security extension key signature and key rotation. By 2017, "snowman plan" has completed the installation of 25 IPv6 (Internet Protocol version 6) root servers in the world. China has deployed 4 of them, which are composed of 1 primary root server and 3 secondary root servers, breaking the dilemma that China did not have a root server in the past.

At the same time, the application of IPv6 is also advancing in an all-round way. On November 26, 2017, the general office of the CPC Central Committee and the general office of the State Council issued the action plan for promoting the scale deployment of Internet Protocol version 6 (IPv6). In June 2018, the three operators jointly announced that they will provide IPv6 services to the outside world in an all-round way, and plan to boost the realization of "IPv6 only" in China's Internet by 2025. On April 16, 2019, the Ministry of industry and information technology issued the notice on carrying out the special action of IPv6 network readiness in 2019, which plans to complete the transformation of 13 Internet backbone direct connection points IPv6 by the end of 2019.

With more and more network transitions, more and more content sites support IPv6, and more and more end users upgrade devices for IPv6 functions, China is becoming the leading force in the development of IPv6 system, firmly holding the fate in their own hands in the new era of Internet.
