CDS (Child DS) and CDNSKEY (Child DNSKEY) [RFC7344] records are used to signal changes in secure entry points. This is one method to maintain delegations that can be used when the DNS operator has no other way to inform the parent that changes are needed. This document elevates [RFC7344] from Informational to Standards Track.

           Managing DS Records from the Parent via CDS/CDNSKEY


   RFC 7344 specifies how DNS trust can be maintained across key    rollovers in-band between parent and child.  This document elevates    RFC 7344 from Informational to Standards Track.  It also adds a    method for initial trust setup and removal of a secure entry point.

   Changing a domain's DNSSEC status can be a complicated matter    involving multiple unrelated parties.  Some of these parties, such as    the DNS operator, might not even be known by all the organizations    involved.  The inability to disable DNSSEC via in-band signaling is    seen as a problem or liability that prevents some DNSSEC adoption at    a large scale.  This document adds a method for in-band signaling of    these DNSSEC status changes.

   This document describes reasonable policies to ease deployment of the    initial acceptance of new secure entry points (DS records).

   It is preferable that operators collaborate on the transfer or move    of a domain.  The best method is to perform a Key Signing Key (KSK)    plus Zone Signing Key (ZSK) rollover.  If that is not possible, the    method using an unsigned intermediate state described in this    document can be used to move the domain between two parties.  This    leaves the domain temporarily unsigned and vulnerable to DNS    spoofing, but that is preferred over the alternative of validation    failures due to a mismatched DS and DNSKEY record.
