Frequently asked questions
Who runs the .sj extension?
Norid A/S is the registry operator for .sj, the country-code extension for Svalbard & Jan Mayen. The registry keeps the list of every .sj name; registrars sell the names to the public.
Can anyone register a .sj domain?
Norid A/S sets who can register .sj names; some country codes need a local address, so check its rules before you buy.
How do I look up who owns a .sj domain?
The .sj registry doesn't publish a public RDAP or WHOIS server listed with IANA, so registration data has to come from the registry's own website.
Is .sj signed with DNSSEC?
Yes. The .sj zone is signed, so a .sj domain can turn on DNSSEC once its registrar adds a DS record.
