1In April, 1993, in order to establish the domain name system in China as soon as possible, the Computer Network Information Center called some network experts from Beijing to inspect the domain name systems in various countries, discussed and preliminarily put forward the domain name system in China.
1994 On May 2 1, with the assistance of Professor Qian and Karlsruhe University in Germany, the computer network information center completed the setting of China's national top-level domain names. CN server, which changed China. CN top-level domain name server has been placed abroad. Qian and Qian respectively served as the management liaison and technical liaison of China CN domain name.
Computer Network Information Center began to provide Internet users in China with the service of registering domain names under CN, and set up WWW servers, Gopher servers and FTP servers on the Internet. Whois server, news server, mail server and other network servers provide directory database services and information services for Internet users in China.
After the CN domain name server moved to China, according to the scheme discussed by domestic experts, the domain name system in China was initially established under CN. Under the top-level domain name CN, there are two-letter second-level domain names and second-level administrative domain names, such as: CO.CN (commercial organization), GO.CN (government organization), OR.CN (non-profit organization), EB.CN (Hebei), EN.CN (Henan), HA.CN (Hainan) and so on. Users are only allowed to register third-level domain names.

At the same time, it announced the establishment of CNNIC Working Committee, and formally authorized China Academy of Sciences to set up and manage China Internet Information Center (CNNIC) to perform the duties of National Internet Information Center.
The promulgation of "Interim Measures for the Administration of Internet Domain Name Registration in China" and the establishment of CNNIC have made the management of CN domain name develop healthily in the direction of legal compliance and orderly management, marking that the development, operation and service of Internet in China have entered the track of continuous improvement and standardization, which is a major event in the development of Internet in China.
According to the Interim Measures for the Administration of Internet Domain Name Registration in China, referring to international practice, the second-level domain name originally composed of two letters will be changed to three letters, while the second-level administrative domain name will still maintain the combination of two letters, but some combinations will be adjusted appropriately. For example, CO.CN, GO.CN, OR.CN, EB.CN (Hebei), EN.CN (Henan), HA.CN (Hainan) and CANET.CN will stop running and be changed to COM.CN, GOV.CN, ORG.CN, HE.CN (Hebei), HA. CN (Henan) and HI.CN (Hainan) respectively. For the third-level domain name originally registered under the name of CANET.CN, users can choose the second-level domain name to register.
On June 3rd, 1997, China Academy of Sciences formally established China Internet Information Center (CNNIC) in the Computer Network Information Center as the national Internet information center.
At the meeting of CNNIC Working Committee on June 5438+1October 65438+March 2000, we heard the work report of CNNIC on June 5438+0999, and suggested that the Ministry of Information Industry revise the Interim Measures for the Administration of Internet Domain Name Registration in China.

On February 4th, 2005, China Internet Network Information Center (CNNIC) officially issued the Rules of Domain Name Transaction Service. The promulgation of this rule will standardize the rapid development of domain name transactions in China and provide a strong guarantee for promoting the optimal allocation of domain name resources.
On July 3rd, 2005, the number of registered CN domain names reached 722,944, making it the largest national top-level domain name in Asia.
