Pv4 Pv6 development of the surplus is exhausted or thorny
has been a matter of fact in the IPv4 address of surplus is exhausted, the Internet transition to IPv6 has entered the implementation phase. China Internet Network Information Center (CNNIC), assistant director Qi Lin said that China has a comprehensive transition to the national domain name system IPv6 initially developed a timetable for 3 years.
China had the opportunity to lead the United States in the commercial IPv6, but in fact, China’s IPv6 is not doing well. Global IPv6 forum chairman Latif Ladid said, China has 137 routers access to IPv6, ranked fourteenth in the world. However, China is applying 32 prefix, can support a very small number of users, while the United States operators to apply for a prefix of IPv6 address of 19, can support the use of millions of users. It can be said that China has almost no IPv6 commercial services provided."
he believes that Chinese operators did not seize the opportunity to turn the IPv4 address into a commercial opportunity for IPv6, or because the Chinese operators of the decision-making level and the government’s technical understanding does not match. But the domestic industry, the emergence of such embarrassing situation, and the relevant administrative departments should grasp the IPv6 address distribution rights association is very large, for IPv6 resources, they take in the national distribution of first come first served, distribution according to needs "principle, Chinese distribution estimation is so little management agencies did not take into account the future development potential for Chinese huge IP address.
is the opposite of China, the United States in recent years, the number of applications in the IPv6 address has been ranked first, and continued rapid growth in recent years, from 2007 to the end of 2010, the United States received a total of more than 1 billion 600 million IPv6 addresses. While in 2010 China assigned to 90 million IPv6 addresses, ranking thirty-second in the world, only about 1/10. This is very similar to China’s performance on the IPv4 a long time ago, a widely circulated argument is: China’s IP address is not a large number of universities in the United states.
based on the status of global IPv4, it is imperative to transition to IPv6. China also began to have a sense of urgency, in 2012, more than half of the national domain name registration services will support IPv6 registration and resolution; and in China in 2013, and strive to achieve our national domain name registration services to fully support IPv6 registration and resolution.
CNNIC and at the same time, in addition to the domain name registration services jointly set up 10 "the next generation of trusted domain name, domain name authority demonstration node" will also work with internet based operators to build 7 "next generation trusted domain name domain name recursive node model".
is a IPv4 address will be used up, IPv6 deployment speed may also be unable to follow, as the most important resource – based network IP address allocation uneven or window temporarily, some Internet users will give great impact. At the same time, the emergence of this situation is also on the Internet
