.cn is the country code top-level domain (ccTLD) for the People's Republic of China. Domain name administration in mainland China is managed through a branch of the Ministry of Industry and Information. The registry is maintained by China Internet Network Information Center (CNNIC), while second-level domain name for educational institutions edu.cn is maintained by China Education and Research Network Information Center (CERNIC, or CERNET), a separated private company.
Any individual may register for second-level domain names. However, the registry has created a set of predefined second-level domains for certain types of organizations and geographic locations. Registrations for such third-level domains were available before second-level domains became available in 2003, and registrants of third-level domains were given priority for names at the second level.
