China Introduces Changes to Internet Domain Name System Hierarchy
As of 2 March this year, the Ministry of Industry and Information Industry (MIIT) introduced a number of changes to the Chinese internet domain name system (DNS) hierarchy.
Among the major changes were the following:
- Domain names may now consist of alphabetic characters (A-Z, a-z, with no differentiation made between lower and upper-case characters), numbers (0-9), a hyphen (-) or Chinese characters, with a dot (.) as the separator between different subdomain names. In the case of Chinese domain names, the separator may be a dot or a Chinese full-stop (。).
- In addition to the national top-level domain names (cn and 中国) several other top-level domain names (in English and Chinese) have now been introduced.

- Below the national top-level domain name (cn), there are two categories of second-level domain names – category domain names and administrative region domain names. In total, there are 34 administrative region domain names, which correspond to China’s provinces, autonomous regions, municipalities and special administrative regions.
