.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.

Second-level domains[edit]

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.

Generic second-level domains[edit]

  • ac.cn : Academic and research institutions
  • com.cn : Industrial, commercial, financial enterprises and individuals
  • edu.cn : Educational institutions (usually universities and colleges)
  • gov.cn : Government departments (both central and local governments)
  • mil.cn : Military organizations
  • net.cn : Networks, NICs and NOCs
  • org.cn : Non-profit organizations

Second-level domains of provinces[edit]

The two-letter abbreviations are the same as those found in GB/T 2260-2002.[3]

Internationalized domain names with Chinese characters[edit]

Internationalized domain names with Chinese characters may be registered at the second level under the .cn top-level domain.

On 25 June 2010, ICANN approved the use of the internationalized country code top-level domains .中国 (China in simplified Chinese characters, DNS name xn--fiqs8s) and .中國 (China in traditional Chinese characters, DNS name xn--fiqz9s) by CNNIC.[4] These two TLDs were added to the DNS in July 2010.

CNNIC proposes Chinese domain names in .公司 (".com" in Chinese) and .网络 (".net" in Chinese). However, these are not recognized by ICANN and are only available via domestic domain name registrar.
