What is .cy?
A little context on Cyprus: the capital is Nicosia, languages include Greek and Turkish, the currency is the Euro (EUR) and the international dialing code is +357.
IANA lists University of Cyprus as the manager of .cy, with an address in Cyprus. The registry's website is http://www.nic.cy. 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 .cy, 4 of them reachable over IPv6. The delegation is DNSSEC-signed, so resolvers can verify that answers for .cy haven't been tampered with on the way.
