On March 17, 2003 (February 15, 2003 lunar calendar), China Internet Information Center opened the registration of CN domain names. China Internet Information Center opened the registration of CN domain names. On March 17, 2003, China Internet Information Center (CNNIC) made a decision to open the registration of CN domain names. For the first time, people came into contact with the concept of CN domain names on a large scale. A small number of investors found business opportunities in this emerging industry and registered many CN boutique domain names. On July 31, 2005, the number of CN domain names registered reached 722,944, making it the country's top-level domain with the largest number of registrations in Asia. On December 31st, the number of CN domain name registrations exceeded 1 million for the first time, reaching 1.09 million, making it the sixth largest national top-level domain in the world. In 2007, CN domain name promoted the "one yuan experience" activity and vigorously popularized domain name investors. In 2008, the "one yuan experience" activity lasted for one year, and even only one yuan was required for renewal. For domain name investors, this is really rare. As of May 2008, the number of national top-level domains in China surpassed Germany for the first time and ranked first in the world. 2009 was a year when the CN domain name was tested again and a year when the CN domain name management system underwent major reforms. Due to the end of the one-yuan CN domain name experience activity, the CN domain name market has been in a state of fluctuation in 2009, and most investors have taken a wait-and-see attitude. Until the second half of the year, a domestic registrar lowered the market price of CN domain names to 3 yuan/year, and the CN domain name market was stable for a time. On December 14, 2009, in order to avoid bad applications of domain names and carry out domain name special project governance actions, CNNIC officially implemented the real-name system of domain names, that is, CN domain name holders must carry out real-name authentication, individuals are not allowed to register new domain names, and enterprises must upload business licenses or organization code certificates to register domain names. The implementation of the domain name system is the first time in the history of CN domain names, which can be said to be unprecedented. It is also a new situation for managers, registrants, and users. In 2010, the domain name system will continue to be fully promoted and implemented.
