       Third Party DNS operator to Registrars/Registries Protocol
            draft-ietf-regext-dnsoperator-to-rrr-protocol-04

Abstract

   There are several problems that arise in the standard
   Registrant/Registrar/Registry model when the operator of a zone is
   neither the Registrant nor the Registrar for the delegation.
   Historically the issues have been minor, and limited to difficulty
   guiding the Registrant through the initial changes to the NS records
   for the delegation.  As this is usually a one time activity when the
   operator first takes charge of the zone it has not been treated as a
   serious issue.

   When the domain uses DNSSEC it necessary to make regular (sometimes
   annual) changes to the delegation, updating DS record(s) in order to
   track KSK rollover.  Under the current model this is prone to delays
   and errors, as the Registrant must participate in updates to DS
   records.

   This document describes a simple protocol that allows a third party
   DNS operator to: establish the initial chain of trust (bootstrap
   DNSSEC) for a delegation; update DS records for a delegation; and,
   remove DS records from a secure delegation.  The DNS operator may do
   these things in a trusted manner, without involving the Registrant
   for each operation.  This same protocol can be used by Registrants to
   maintain their own domains if they wish.
