.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).

Second-level domains

Registrations are taken at the second level and also at the third level beneath various categorized second level names. A second-level registration automatically blocks the name from registration by anybody else under any of the third-level names.

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

Restricted registration:

• .gov.lk: Governmental departments of Sri Lanka (automatically reserves name at second level and under all other second level names)
• .ac.lk: Research and higher education institutions in Sri Lanka
• .sch.lk: Registered schools in Sri Lanka
• .net.lk: Licensed internet service providers in Sri Lanka
• .int.lk: International treaty organizations

Open registration:

• .com.lk: Commercial entities
• .org.lk: Noncommercial organizations
• .edu.lk: Educational sites
• .ngo.lk: Non-governmental organizations
• .soc.lk: Registered societies
• .web.lk: Web sites
• .ltd.lk: Limited liability companies
• .assn.lk: Associations
• .grp.lk: Groups of companies
• .hotel.lk: Hotels
