.hk is the designated Internet country code top-level domain (ccTLD) for Hong Kong. Hong Kong Internet Registration Corporation (HKIRC) is the only organization endorsed by the Hong Kong Government to undertake the administration of 'hk' domain names. Hong Kong Internet Registration Corporation (HKIRC) is a non-profit making, non-statutory, member-based corporation established in 2001.

From its inception in 1990 until 2002, the domain was administered by the Joint University Computer Centre. In 2002, through a "Memorandum of Understanding" with the Hong Kong government, HKIRC took over the administration of '.hk', while the Hong Kong Domain Name Registration Corporation Limited (HKDNR), its wholly owned subsidiary of HKIRC, is responsible for the day-to-day management of the registration service for Specific '.hk' Domain Names and Generic '.hk' Domain Name (e.g., www.myname.hk). '.hk' domain names can be registered at both the second and third level.
