.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)
