What is .한국?
IANA delegated .한국 on February 6, 2011, as part of the effort to let people use domain names entirely in their own script.
A little context on South Korea: the capital is Seoul, the main language is Korean, the currency is the South Korean won (KRW) and the international dialing code is +82.
South Korea shares land borders with 1 country, so the ccTLDs next door are .kp (North Korea).
IANA lists KISA (Korea Internet & Security Agency) as the manager of .한국, with an address in Korea (the Republic of). The registry's website is http://www.nic.or.kr. ccTLD managers set their own policies — who can register, which second-level names exist, pricing to registrars — so those rules differ from country to country.
On the technical side, .한국 is served by 6 authoritative name servers, 4 of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .한국, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.kr).
South Korea also has another country-code domain in the root zone: .kr.
