Report on ENDS0 stuff: My proposal is to mandate EDNS0 for IPv6 transport. That is, DNS servers/resolvers MUST use EDNS0 if DNS querys/answers are carried over IPv6. There is another proposal from DNSEXT wg, described in draft-ietf-dnsext-message-size-00.txt. It is to mandate EDNS0 for A6. That is, DNS servers/resolvers MUST use EDNS0 if they support A6. In this morning, at the session of DNSEXT, Olafur Gudmundsson, one of co-chairs of the wg and the author of message-size, made presentation on message-size. I explained about my proposal after him. My proposal is DNS-transport oriented while Olafur's one is DNS-contents oriented. In other words, my proposal is IPv6 specific as Olafur's one is DNS specific. Impression is that we can pick up both proposals since they are not contradictional. Olafur suggested me that my proposal be included in "IPv6 Host Requirements", on which Marc Blanchet is working. There were no strong objections araised against this from those who were in the DNSEXT session. If there are no objections from IPNG wg, I will help Marc to get the draft out. P.S. The minimum size of resolver's buffer is defined 1280 by both ENDS0 and message-size. This means that UDP payload size can be 1280, so DNS/IPv6 would be fragmented at servers. Some of us believe that we need to change 1280 to a smaller value. Discussions are going on at the DNSEXT ml (namedroppers).
