What is .இலங்கை?
IANA delegated .இலங்கை on August 18, 2010, as part of the effort to let people use domain names entirely in their own script.
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 LK Domain Registry as the manager of .இலங்கை, 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, .இலங்கை is served by 6 authoritative name servers, 5 of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .இலங்கை, which lets validating resolvers check its answers cryptographically.
Sri Lanka also has other country-code domains in the root zone: .lk and .ලංකා (Sinhala).
Same registry, other endings
