.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.
