LK Domain Naming Structure

The LK domain, in common with many other countries, places most organizations at the second level, immediately to the left of the .lk, irrespective of the type of organization.

E.g.: myorg.lk

All registrations under the top-level domain ensure that the domain name is blocked in all open second levels provided that the second level domain is available. If they wish to use open second level domain names in addition to the top level domain, it can be done by configuring DNS entries for the open second level domain, but DNS for both top level and second level domain should be hosted on the same machine.

• Sinhala and Tamil Domain Names
The Registrants can request for Sinhala and Tamil domain names in the forms “.ලංකා”and “.இலங்கை”onthe LK Domain Registry.

The .lk domain registrant(s) can request for the relevant Sinhala and Tamil domain(s) to the existing .lk domain(s) Free of Charge (FOC), through the online request form available on the LK Domain registry official website. The requested domain name should be derived from the existing .lk domain name by transliteration or pronunciation.
