I support the concept of a range of RR values reserved for the
parent-side of the zone cut, such that DNS implementations can process
future ones automatically instead of having to have special-case code
for each one.
I support this too.
I note also Shumon's draft wanting to carve out a sub-range of the
private RR values for private / testing meta-RRs.
For those who haven't seen it, that draft is:
https://datatracker.ietf.org/doc/html/draft-huque-dnsop-private-
metatypes-01 <https://datatracker.ietf.org/doc/html/draft-huque-dnsop-
private-metatypes-01>
On whether these two features merit documents of their own I have no
particular opinion, but either way the IANA registry for which the
reserved ranges are enumerated in RFC6895 will need updating, ideally
(IMHO) in an RFC6895(bis).
One of the 'Open Questions' in our draft asked exactly that question.
Ideally,
RFC6895 would be the best place to make any updates to the RR type space
classification. But I'll note that both these drafts go a bit beyond IANA
considerations, e.g. Roy's draft talks about interaction with the
proposed DE
EDNS header flag. And mine talks about the correct response behavior for
unknown Q and Meta-Types (I was contemplating renaming our doc to 'On Q
and Meta-Types in the DNS" to acknowledge the expanded scope.
I think it would be reasonable to have 'QTYPE handling amendments and
clarifications' document with an IANA Considerations section in it. IMHO
better to keep it under one roof/document.
