.lk

.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

Internationalized top-level domains
In September 2010 two new internationalized top-level domains were registered for Sri Lanka. They became active during 2011.
 * .ලංකා (for domain names in the Sinhala language)
 * .இலங்கை (for domain names in the Tamil language)
