In 1998, China introduced IPv6. In 2003, IPv6 was put on the timetable. However, China has been preparing IPv6 for more than ten years, and the current mainstream is still IPv4. Now that the country is accelerating the deployment of IPv6 scale, the reason is that there are six main reasons why IPv6 is struggling.
It is understood that IPv6 was first introduced to China from CERNET in 1998. As early as 2003, China put the development of IPv6 on the agenda. This is a very correct and timely strategic decision. After five years of development, the first phase was booked. The strategic goal, but since 2008, the development speed of China's IPv6 has begun to slow down and began to lag behind the international level. It is really a long time, but it has caught a late episode.
First , the trap that falls into the private address is difficult to dial. The address translation (NAT) can temporarily deal with the problem of insufficient IPv4 public network address. However, the management of the private address across multiple public addresses is quite complicated. NAT destroys the end. The transparency of the end is not traceable to the user.
Second, the government lacks clear market orientation and application of prior awareness. In developed countries, the military and the government generally switch to IPv6, and the website of our national government has not played its leading role.
Third, the bottleneck of content services is not enough and there is no favorable policy. "The port of China's entire IPv6 is not open, the international bandwidth is not enough, and the foreign IPv6 service has not landed in China. The migration of IPv6 on applications and websites is lagging behind. These have seriously dragged down the development of IPv6 in China.
4. Some misunderstandings and interference have affected the implementation of the national IPv6 strategy. He said that some of the programs that have isolated the Chinese public Internet from the Internet have confuse some units with "independent innovation, security and reliability", violating China's insistence on a global Internet. In addition, it is thought that the future network that subverts IP will be realized soon, while waiting for a wait-and-see state, the IPv6 deployment will not move.
Fifth, the Internet lacks due international competition. Large ISPs such as Google and Facebook have already migrated a large number of applications to IPv6. Some ISPs in China have also made some application migrations, but deep-level services are not provided.
Sixth, China's Internet security regulatory measures are costly and costly. On IPv6, the entire migration needs to be rebuilt.
6.1 Migration complexity
To move smoothly from IPv4 to IPv6, companies must audit, review, upgrade, reconfigure, and test their entire technology infrastructure, from routers and servers to smartphones, PCs, laptops, and other connected devices. Changes are needed to achieve change, and the way companies operate and make policies must change accordingly.
6.2 Problem of return on investment
In view of the complexity of the migration process, it involves many time and money costs, in addition to the cost of software and hardware upgrades, the company needs to plan and execute in a timely manner. The investment cost is too large, but the revenue is very low. Therefore, neither the hardware manufacturer nor the ISP has enough market driving force to promote the large-scale network transformation of IPv6. On the other hand, in the migration from IPv4 to IPv6, there is no ideal smooth evolution scheme, and there is no small risk problem.
6.3 Traditional hardware issues
When a transition occurs, the networked device may require a dual stack configuration: an IPv4 address and an IPv6 address. Older devices that do not support IPv6 addresses can cause network communication problems and eventually become a burden. Terminals are shortcomings in the development of IPv6. Currently, most commercial fixed-line terminals and mobile phones do not support IPv6.
Measures to accelerate the deployment of IPv6 scale:1. 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 the Internet Protocol Version 6 (IPv6), which clearly stated three main objectives: at the end of 1.2018, the number of IPv6 active users reached 200 million, in the Internet users. The proportion in the middle is no less than 20%; at the end of 2.220, the number of active IPv6 users exceeds 500 million, accounting for more than 50% of Internet users, and the new network address no longer uses private IPv4 addresses; at the end of 3.2025, networks, applications, The terminal fully supports IPv6 and completes the smooth evolution and upgrade to the next generation Internet.
In order to implement the spirit of the Central Office and the State Council's Action Plan for Promoting the Deployment of the Internet Protocol Version 6 (IPv6), the Qinhuangdao Development Zone Management Committee has already launched its government website under the strong support of the National Next Generation Internet Industry Technology Innovation Strategic Alliance. And 88 management modules, such as branch offices, all implement IPv6 upgrades.
Second, the next-generation Internet National Engineering Center recently officially announced the launch of IPv6 public DNS: 240c::6666, alternate DNS: 240c::6644. This is a free DNS service for the public. It will undoubtedly provide an excellent choice for IPv6 users around the world to optimize the Internet experience. Its precise, fast, secure and stable DNS64 features will fully guarantee the efficiency and stability of the IPv6 network.
As a result, China's network environment will undergo earth-shaking changes in the next few years, let us wait and see.
