What is .az?
A little context on Azerbaijan: the capital is Baku, languages include Azerbaijani and Russian, the currency is the Azerbaijani manat (AZN) and the international dialing code is +994. It's landlocked.
Azerbaijan shares land borders with 5 countries, so the ccTLDs next door are .am (Armenia), .ge (Georgia), .ir (Iran), .ru (Russia) and .tr (Türkiye).
IANA lists IntraNS as the manager of .az, with an address in Azerbaijan. The registry's website is http://www.whois.az. 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, .az is served by 4 authoritative name servers, 2 of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .az, which lets validating resolvers check its answers cryptographically.
