.cn is the country code top-level domain (ccTLD) for the People's Republic of China. Introduced on 28 November 1990, the domain is administered by China Internet Network Information Center, a public institution affiliated with the Ministry of Industry and Information Technology. The domain is the largest ccTLD in the world.[4]
The Chinese script internationalized country codes are ".中国" ("China" in Simplified Chinese) and ".中國" ("China" in Traditional Chinese). Entities connected to Hong Kong, Macau, and Taiwan typically use .hk, .mo, and .tw, respectively,[5] despite the availability of corresponding second-level domains under .cn for those regions.
