What is .lt?
A little context on Lithuania: the capital is Vilnius, the main language is Lithuanian, the currency is the Euro (EUR) and the international dialing code is +370.
Next door on the map, you'll find .by for Belarus, .lv for Latvia, .pl for Poland and .ru for Russia.
IANA lists Kaunas University of Technology as the manager of .lt, with an address in Lithuania. The registry's website is http://www.domreg.lt. ccTLD managers set their own policies — who can register, which second-level names exist, pricing to registrars — so those rules differ from country to country.
Under the hood, the root zone points to 6 name servers for .lt, 4 of them reachable over IPv6. The delegation is DNSSEC-signed, so resolvers can verify that answers for .lt haven't been tampered with on the way. Registration data is published over WHOIS (the WHOIS server is whois.domreg.lt).
