This year, the management and operation of the Internet's top-level domain names have undergone unprecedented and critical changes. On November 13, the domain name registration organization Public Interest Registry (PIR) announced that it would be acquired by a private investment company. This move means that PIR will transform from an NGO non-profit organization to a for-profit entity.
PIR currently manages the .org top-level domain name, and the outside world believes that the change in corporate attributes means that the cost of .org domain names is likely to increase.
In fact, in June this year, ICANN approved the removal of the price cap on the .org domain name, which is equivalent to paving the way for subsequent price increases. In addition, the price caps of the two major domain names .info and .biz were also removed this year.
It is worth mentioning that my country has been accelerating the layout of IPv6. Since 2016, China's IPv4 address growth has basically stopped. In China, any expansion of the scale of the IPv4 Internet must be achieved through various forms of address sharing using network address translation methods (NATs).
Unfortunately, there is no public data on NAT use in China or any other country, but the number of users itself can explain the data problem. We know that there are about 301 million IPv4 addresses serving 741 million Internet users in China. Some users may have multiple connected devices, while others may share a single device to connect to the Internet. It is reasonable to estimate that there are more than 1 billion devices in China, which means that the average IPv4 address sharing rate is about 3 devices/IP address.
Among these operator networks, one network operator has been supporting IPv6 for many years, namely China Education and Research Computer Network CERNET, AS 4538. Although there may be some changes in the measurement results of utilization rate due to changes in the measurement environment and the network itself, CERNET's IPv6 utilization rate has been around 30% for many years.
According to the latest data from the China Internet Network Information Center, there are only 338 million IPv4 addresses for 751 million Internet users in my country, which cannot meet the needs of my country's Internet development. IPv6 is designed with 2 to the power of 128 addresses, which means that every grain of sand on the earth can be assigned an IPv6 address, solving the problem of address scarcity.
The Action Plan for Promoting Large-Scale Deployment of Internet Protocol Version 6 (IPv6) issued by the General Office of the CPC Central Committee and the State Council at the end of last year mentioned that by the end of 2018, a market-driven benign development environment will be basically formed, and the number of active IPv6 users in my country will reach 200 million, accounting for no less than 20% of Internet users. This means that after India and the United States, my country will become the third country in the world with more than 100 million IPv6 users.
