.hk is the Internet country code top-level domain (ccTLD) for Hong Kong. It was created in 1990.

Until 2004 there were very few second-level domains under .hk, as it was normally only possible to register third-level domains. The following are the main third-level domains:

.com.hk - commercial entity

.edu.hk - educational institutions

.gov.hk - government

.idv.hk - individuals

.net.hk - network service providers

.org.hk - non-profit organizations

and for historical reasons, the following institutes are registered as second-level domains:

.cuhk.hk - Chinese University of Hong Kong (later changed to .cuhk.edu.hk),

.hku.hk - The University of Hong Kong,

.ust.hk - The Hong Kong University of Science and Technology,

However, as of 2004 it became possible to register second-level .hk domains, so these will soon become common.
