The latest statistics show that, as of August 2017, 25 IPv6 rootsThe serverA total of 2391 recursive server queries have been received worldwide, mainly distributed in Europe, North America and the Asia Pacific region, which reflects the global IPv6 network deployment and user development to some extent. From the traffic point of view, the IPv6 root server receives queries nearly 120 million times a day.
Root server is responsible for the Internet's top-level domain name resolution, known as the "central nervous system" of the internet". The root server governance system dominated by the first mover advantage in the United States has lasted for nearly 30 years. In the past IPv4 (Internet Protocol fourth version) system, a total of 13 root servers worldwide, the only main root deployed in the United States, the remaining 12 auxiliary roots have 9 in the United States, 2 in Europe, 1 in japan.
Engineering Center Director Liu Dong told Xinhua that the cause of the global governance system is a key Internet resource management and allocation is not balanced; on the other hand, the lack of the root server to enable countries against large-scale distributed denial of service attack ability is insufficient, for all the Internet Security risks.
With the increasing number of Internet access devices, the original IPv4 system has been unable to meet the demand, IPv6 protocol began to spread around the world.
Liu Dong said that the engineering center to seize this opportunity in 2013 with Japan and the United States related operating agencies and professionals launched the "snowman plan", put forward a set of root servers based on IPv6 for new applications, self controlled solutions and technology system.
Fully compatible with the existing IPv4 root server architecture based on "snowman plan" in 2016 in the United States, Japan, India, Russia, Germany, France and other 16 countries in the world to complete 25 IPv6 root server set up, of which 1 units and 3 sets of root root deployment in China, actually formed a new pattern 13 original plus 25 IPv6 root root, a solid foundation for the establishment of a multilateral, democratic and transparent international Internet governance system.
