What is .sj?
A little context on Svalbard and Jan Mayen: the capital is Longyearbyen, the main language is Norwegian, the currency is the krone (NOK) and the international dialing code is +4779.
IANA lists Norid A/S as the manager of .sj, with an address in Norway. The registry's website is https://www.norid.no/en/omnorid/toppdomenet-sj. 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, .sj is served by 6 authoritative name servers, every one of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .sj, which lets validating resolvers check its answers cryptographically.
