.cn is thecountry code top-level domain (ccTLD) for thePeople's Republic of China. Introduced on 28 November 1990, the domain is administered byChina Internet Network Information Center, a public institution affiliated with theMinistry of Industry and Information Technology. The domain is the largest ccTLD in the world.[4]

TheChinese scriptinternationalized country codes are ".中国" ("China" in Simplified Chinese) and ".中國" ("China" in Traditional Chinese). Entities connected toHong Kong,Macau, andTaiwan typically use.hk,.mo, and.tw, respectively,[5] despite the availability of corresponding second-level domains under .cn for those regions.

The provincial-level administrative divisions second-level domains are with the open-registration policy.

Internationalized domains

[edit]

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

On 25 June 2010,ICANN approved the use of theinternationalized country code top-level domains ".中国" (China insimplified Chinese characters, DNS namexn--fiqs8s) and ".中國" (China intraditional Chinese characters, DNS namexn--fiqz9s) by CNNIC.[8] These two TLDs were added to the DNS in July 2010.

CNNIC proposed around this time Chinesedomain names in ".公司" (".com" in Chinese) and ".网络" (".net" in Chinese). However, these have not been recognized byICANN yet and are only available via domesticdomain name registrars.

Around 15 other generic domain names with Chinese characters have later been registered. SeeList of Internet top-level domains#Chinese characters.
