Description

Update the registrant contact on a domain in place — name, company, email, phone and address. Use it to correct contact details on a domain you own. The registry may email the owner to confirm the change before it takes effect (ICANN/registry rules, and.se/.nu especially). This edits the existing contact; it does not change the legal owner (organisation / org-nr) — that is request_owner_change, which is BankID-signed.
