Country-code top-level domainsDNSSEC
Overview
.lt is the Internet country-code top-level domain (ccTLD) designated for Lithuania. Managed through the DOMREG service of Kaunas University of Technology, .lt is used primarily by entities connected with Lithuania and allows second-level registrations. The registry supports internationalized domain names (IDN) and DNSSEC.
History
- Introduced and delegated by IANA on 3 June 1992.
- Initial external administration was handled by the University of Oslo.
- In 1994 administration was re-delegated to Kaunas University of Technology (KTU).
- Early second-level registrations occurred in 1993; first examples include mii.lt, ktu.lt, and vu.lt.
- The registry division at KTU has operated under various internal names and, since 1 March 2018, is known as the Internet Service Centre. The registry commonly uses the DOMREG trademark.
