2) The recommendation that name servers MUST support EDNS0 if they're

the message size exceeds 1200 octets is less obvious: it seems to
me that EDNS0 is enough.
Has anyone done any analysis of current OS'es and their supported UDP
fragment reassembly size? I don't expect any problems, but if there's a
problem here then ENDS0 won't be good enough, and the client will have
to fall back to TCP no matter what.
Maybe this has already been discussed, but I joined "recently" (compared
to so many others of you).
