DNS Registration Model

The DNS registration model tracks registrar-zone assignments and registration lifecycle attributes.

• dns_registrar (DNS Registrar, mandatory): Registrar used.
• dns_zone (DNS Zone, mandatory): Zone that is registered.
• status (Status, mandatory): Registration status.
• expiration_date (date, optional): Domain expiration date.
• auto_renewal (boolean): Whether auto renewal is enabled.
• registry_locked (boolean): Whether registry lock is enabled.
• transfer_locked (boolean): Whether transfer lock is enabled.
• privacy_enabled (boolean): Whether privacy protection is enabled.
• website_forwarding_enabled (boolean): Whether website forwarding is enabled.
• renewal_term_months (integer, optional): Renewal term in months.
• dnssec_enabled (boolean): Whether DNSSEC is enabled.

Uniqueness is enforced for registrar and zone together, and each zone can only have one registration.
