Is what is proposed in this draft a matter of interest to the DNS Operations Working Group? If so, the document could have been brought to the attention of the relevant working group before the Last Call. That doesn't preclude the draft from being an individual submission. The IAB Stream might be more appropriate though, given the area it covers.

The intended status of this draft is Standard Track. As the proposal is about operations, BCP looks like a better fit. The proposal could be fitted into an update of BCP 49, with the removal of the parts of RFC 3152 that have been obsoleted by RFC 3596.

Quoting the IANA Considerations section of RFC 3152:

  "This memo requests that the IANA delegate the IP6.ARPA domain
   following instructions to be provided by the IAB.  Names within this
   zone are to be further delegated to the regional IP registries in
   accordance with the delegation of IPv6 address space to those
   registries.  The names allocated should be hierarchic in accordance
   with the address space assignment."

And Section 4 of RFC 3172:

  'The IPv4 reverse address domain, "in-addr.arpa" is delegated to the
   IANA.  The "in-addr.arpa" zone is currently located on the same same
   subset of the root servers  as "arpa".  Sub-delegations within this
   hierarchy are undertaken in accordance with the IANA's address
   allocation practices.'

  'The "ip6.arpa" IPv6 reverse address domain uses a method of
   delegation that is the same as is used for "in-addr.arpa", where the
   "ip6.arpa" domain is delegated to the IANA, and names within this
   zone further delegated to the regional IP registries in accordance
   with the delegation of IPv6 address space to those registries'

Section 1 of this draft states that:

  "The choice of operators for individual nameservers is beyond the
   scope of this document, and is an IANA function"

That is once again repeated in the IANA Considerations Section of this draft. I don't have any comment about that statement at this time except to say that it would be useful to know what IANA plans to do.

Although it may not be the intent of the authors of this draft to do so, the proposal may set the bounds of what the IETF can or cannot do in relation to RFC 2860.

Section 4 of this draft contains a (proposed) IAB Statement. As this is a Last Call, I expect that the subject of this draft has come up in discussions between the IESG and the IANA liaison and that IAB has been informed. There is no mention of the matter in IESG or IAB minutes.

Section 6 of RFC 3172 mentions that any new subdomain delegation must adequately document any security considerations specific to the information stored therein. Irrespective of whether this proposal is about a new subdomain delegation of not, it would be informative to the reader if Section 6 of this draft did more than say that it introduces no additional security risks for the Internet.
