Change nameserver delegation (vanity sets only)

PUT /domains/{domain}/nameservers

Operation ID: PutNameserversByDomain

Delegates the domain to one of the account’s vanity nameserver sets (vanity_set_id), or reverts it to the regfish standard nameservers (vanity_set_id: null). Free-form nameservers are intentionally NOT supported on this endpoint, externally hosted delegations must be managed in the regfish dash.

Guarded by the Domain-Guardian (ns_change rule class), domain status checks (pending transfer, cancellation) and a daily per-domain change limit.
