What is .ua?
A little context on Ukraine: the capital is Kyiv, the main language is Ukrainian, the currency is the Ukrainian hryvnia (UAH) and the international dialing code is +380.
Next door on the map, you'll find .by for Belarus, .hu for Hungary, .md for Moldova, .pl for Poland, .ro for Romania, .ru for Russia and .sk for Slovakia.
IANA lists Hostmaster Ltd. as the manager of .ua, with an address in Ukraine. The registry's website is https://www.hostmaster.ua. 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 7 name servers for .ua, every one of them reachable over IPv6. The delegation is DNSSEC-signed, so resolvers can verify that answers for .ua haven't been tampered with on the way. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.ua).
Ukraine also has another country-code domain in the root zone: .укр (Cyrillic).
