What is .aq?
IANA lists Antarctica Network Information Centre Limited as the manager of .aq, with an address in New Zealand. 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 3 name servers for .aq, every one of them reachable over IPv6. There is no DS record for .aq in the root zone, which means the TLD is not DNSSEC-signed at the top level.
