Ed, can you suggest an appropriate change to the draft-ietf-dnsop-ipv6-transport-guidelines-02 and let's reflect that accordingly in draft-ietf-dnsop-ipv6-dns-issues-06.txt.
In another reply I had (part of) this, which I think is balanced as far as v4-v6, doesn't mandate "v4 forever", and is fuzzy enough to be re-interpreted later:
# Regardless of what is in a zone, there should be a server for it available # on all network layers, e.g., IPv4 and IPv6, in common use. A zone's contents # should appear the same on all servers, hence, no matter what network layer # used to query the servers, the contents of the answer is substantially the # same.
"In common use" - means that even if you don't have a v4 infrastructure anymore, you should consider asking someone with one to server your zones for you on a v4-enabled server.
"Substantially" - because of the glue question and the truncation issue in DNS, you can't specify that the answer "is" the same.
Another case to consider is the the query type any. If my v4 recursive server does not share the same memory (RAM) as my v6 server, chances are strong that the caches in the two will differ over time. QTYPE ANY queries ask for "what you have" about a name, not the complete data at the name (as far as an authoritative server is concerned). It's reasonable to consider that the exact responses from the two servers will differ, regardless of the fact that they are on different network layers.
(IMHO, it's still worth keeping in a summary of draft-ietf-dnsop-ipv6-transport-guidelines-02 in draft-ietf-dnsop-ipv6-dns-issues-06.txt, because let's be honest -- an average john doe isn't going to read it in any case :)
I've got the feeling I'm going to need to try again at the wording, I'm running up on a meeting deadline.
