What is .ad?
A little context on Andorra: the capital is Andorra la Vella, the main language is Catalan, the currency is the Euro (EUR) and the international dialing code is +376. It's landlocked.
Andorra shares land borders with 2 countries, so the ccTLDs next door are .fr (France) and .es (Spain).
IANA lists Andorra Telecom as the manager of .ad, with an address in Andorra. The registry's website is https://www.domini.ad. 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.
On the technical side, .ad is served by 4 authoritative name servers, every one of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .ad, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.nic.ad).
