.lk is the Internet country code top-level domain (ccTLD) for Sri Lanka. Foreign companies who do not have a local presence can only reserve their top-level and corresponding open second-level domains (either through the LK Domain Registry or agents). In order to register and use a name they must have a contact address in Sri Lanka (which may be obtained through an agent or law firm).

These second-level names are available for registrations within them: Restricted registration: Open registration:
