.kr is the Internet country code top-level domain (ccTLD) for South Korea. Registrations are processed via registration agents.
From September 2006, it became possible to register domain names directly under .kr (although this is currently only possible for internationalized domain names).
Trademark holders and public bodies benefited from an "early registration period", after which the owners of .kr third-level domains had priority to get the corresponding second-level domains.
In 2011 a new top-level domain was registered for South Korea, intended for domain names in the local language. The top-level domain is domain names and working sites became active during 2011.
.kr domains are sometimes used as domain hacks such as flic.kr, an alternative address for Flickr.
