It's been a while, but I have put up a new version of the MIXFR draft:
https://tools.ietf.org/html/draft-mekking-mixfr-02
The draft speaks of an OPCode in the IANA section and of a meta
RRType in the examples and Introduction section, which is it?
Probably copy paste error from a different draft. MIXFR is a new query
type, so that's an error in the IANA section. The intention is to
request a new RRtype. Thanks for catching this.
If it is an RRType, some words need to be added about the fact that
current resolvers will pass through the MIXFR query and not reply with
NOTIMPL. In a similar vein, unaware auths will respond with an NXDOMAIN
or (more likely) a NODATA in that case.
IXFR solved this by saying "If the query type is not recognized by the
server, an AXFR (preceded by a UDP SOA query) should be tried, ensuring
backward compatibility." Probably MIXFR can say something similar.
A resolver should behave similar for MIXFR as it does for AXFR and IXFR.
I can't find words about this in RFC 1995 or RFC 5936, so I am not sure
if this document should add something about that.
Groeten,
Matthijs
