Less than 1% of our country will speed up IPv6 development.

In early January, the next generation of Internet public DNS national engineering center officially announced the launch of IPv6, and in Beijing, guangzhou, Chicago, London, Frankfurt, etc to deploy the recursive node, will provide free public DNS service to the world.
In 2017, the plan for the implementation of the sixth version of the Internet protocol (IPv6) deployment plan has also been made clear. By the end of 2018, the number of IPv6 active users in China will be 200 million, and by 2020 it will reach 500 million.In fact, governments around the world are now stepping up their deployment of IPv6.
In fact, the country has been looking forward to developing IPv6 on the agenda as early as 2003 in response to the growing problem of IPv4 addresses.

achieved.However, since 2008, the development rate of IPv6 has started to slow down, and it is gradually falling behind the international level, which is "getting up early and catching the late set."
Early start is lower than international level.
According to the APNIC Labs to provide global IPv6 users (estimated) and the penetration of IPv6 users report, by the end of 2017, world IPv6 users of the top 10 countries/regions, followed by India, the United States, Germany, Japan, Brazil, Britain, France, Canada, Belgium, Malaysia, China came 14th;China is ranked 67th in the global ranking of IPv6 users.

over the past decade, China has been struggling with the development of IPv6.
Wu jianping, an academician at the Chinese academy of engineering and a professor at tsinghua university, said that there are several reasons for such a backward situation today:
First, use on the Internet technology in our country is still relatively backward and started relatively late, lead to address shortages, caused by private address export into a public address, however the address translation (NAT) can only be temporary deal with IPv4 public addresses the problem of insufficient, together with the whole industry chain of IPv6 is unmoved.
Receive operator services abroad, a user must have a public address, but not necessarily in China in this way, one is you choose, but don't have the consciousness to select a public address.
Second, the Internet should be lack of international competition, like Google, Facebook and other large Internet service provider (ISP) has applied a lot of migration to IPv6, although some domestic ISP also did some application migration, but does not provide a deeper level of service, the domestic part of the ISP is not in a big international competition environment in the world.
In addition, operators and information providers to complain about each other, each other operators complain that isps don't do application migration, users do not have access to resources, ISP complain operator without developing user resources for anyone, in fact all of these are not long-term strategic vision.
Moreover, the cost and cost of China's Internet security supervision measures are high, and the application of the whole migration to IPv6 needs to be rebuilt.
In addition, some security experts believe that IPv6 itself is capable of end-to-end encryption, which makes it difficult for many security management in our country.In fact, why the Internet is encrypted on IPv6 and IPv4 is not, is to let users have security measures, which is undoubtedly good for users.
Speed up the deployment of IPv6.
Recently, the next generation Internet national engineering center officially announced the launch of IPv6 public DNS: 240c: 6666 and standby DNS "240c::6644".
Through the free public DNS service performance, for the majority of IPv6 Internet users build safe, stable, high-speed, intelligent Internet experience, boost our country "to promote the Internet protocol version 6 (IPv6) scale deployment action plan fully implemented.
At the same time, the engineering center has also launched a global promotion program for IPv6 public DNS (IPv6 Forum), which aims to provide better Internet service for users around the world.
In addition, IPv6 public DNS will reduce the recursive process by actively synchronizing com/net domain names, cache hot domain names, etc., to maximize the quick response.Public DNS security, IPv6 support single IP the analytical speed, DNSSEC safety verification, through safe speed limit can effectively intercept the malicious attacks, etc., will not appear malicious jump, there will be no mandatory advertising appeared.
Finally, even a pure IPv6 user can implement a request for a pure IPv4 network resource based on the DNS64 resolution service.
On the other hand, with rapid deployment, global IPv6 network equipment mainstream manufacturers also issued a large number of IPv6 products in recent years, basic covers the existing IPv4 product type (including routers, switches, access server, firewall, VPN gateway, DNS server, etc.), so that enough to meet the demand of commercial deployment.
In IPv6 Ready Logo devices, routers, switches, firewall, gateway equipment in China is ahead of other types of products, compared to other large network equipment such as the United States, South Korea, Japan, China, in the large equipment such as routers, switches, safety devices, more than 70%, and other equipment types, particularly in terms of terminal equipment application is relatively small.
In other words, who can take the lead in IPv6 and who will be able to take advantage of the competition in the future.
On the hardware side, devices such as mobile phones and PCS, which have been launched in the last two or three years, have largely supported IPv6.
In addition, the operating system as the basis of a variety of applications, the most important link is also supports IPv6, at present, the common operations, including mobile phones, PC and server system, basic IPv6, can apply approval rating at 90%.
In fact, in the last year the promoting Internet protocol version 6 (IPv6) scale deployment action plan has been made clear that in the end of 2018 to achieve domestic IPv6 active users reached 200 million, 2020 to 2020.
