What is .lk?
Why .lk? The letters come from Lanka, as in Sri Lanka.
A little context on Sri Lanka: the capital is Colombo, languages include Sinhala and Tamil, the currency is the Sri Lankan rupee (LKR) and the international dialing code is +94.
Sri Lanka shares land borders with 1 country, so the ccTLDs next door are .in (India).
IANA lists Council for Information Technology LK Domain Registrar as the manager of .lk, with an address in Sri Lanka. The registry's website is http://www.domains.lk. 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, .lk is served by 8 authoritative name servers, 7 of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .lk, which lets validating resolvers check its answers cryptographically.
Sri Lanka also has other country-code domains in the root zone: .ලංකා (Sinhala) and .இலங்கை (Tamil).
