                 Revised IANA Considerations for DNSSEC
                  draft-ietf-dnsop-dnssec-iana-cons-00

Abstract

   This document changes the review requirements needed to get some
   DNSSEC algorithms and resource records added to IANA registries.  It
   updates RFC 6014 to include hash algorithms for DS records and NSEC3
   parameters.  It also updates RFC 5155 and RFC 6014, which have
   requirements for DNSSEC algorithms.  It also updates RFC 8624 to say
   that algorithms that are described in RFCs that are not on standards
   track are only at the "MAY" level of implementation recommendation.

1.  Introduction

   DNSSEC is primarily described in [RFC4033], [RFC4034], and [RFC4035].
   DNSSEC commonly uses two resource records beyond those defined in RFC
   4034: DS [RFC3658] and NSEC3 [RFC5155].

   [RFC8126] describes the requirements for listing in the myriad IANA
   registries.

   [RFC6014] updated the requirements for how DNSSEC cryptographic
   algorithm identifiers in the IANA registries are allocated, reducing
   the requirements from being "Standards Action" to "RFC Required".
   However, the IANA registry requirements for hash algorithms for DS
   records and for the hash algorithms used in NSEC3 are still
   "Standards Action".

2.  Update to RFC 6014

   This document updates RFC 6014 to bring the requirements for DS
   records and NSEC3 hash algorithms in line with the rest of the DNSSEC
   cryptographic algorithms by allowing any DS or NSEC3 hash algorithms
   that are fully described in an RFC to have identifiers allocated in
   the IANA registries.

3.  Update to RFC 8624

   This document updates [RFC8624] for all DNSKEY and DS algorithms that
   are not on standards track.

   The second paragraph of Section 1.2 of RFC 8624 currently says:

   This document only provides recommendations with respect to
   mandatory-to-implement algorithms or algorithms so weak that they
   cannot be recommended.  Any algorithm listed in the [DNSKEY-IANA] and
   [DS-IANA] registries that are not mentioned in this document MAY be
   implemented.  For clarification and consistency, an algorithm will be
   specified as MAY in this document only when it has been downgraded
   from a MUST or a RECOMMENDED to a MAY.

   That paragraph is now replaced with the following:
