break out of the MTU 1500 jail some day or the internet will end in
header processing related heat death. some work is being done and some
results are already known. we should be open to the possibility of
improvement.
If there is interest in pursuing DNS-specific methods for learning and
using path MTU values, where would the right venue for that be?
there used to be a dns-research@ mailing list over at oarc. maybe ask
them to rekindle same? applying PLPMTUD to DNS should be
straightforward, and would be a great IETF Hackathon goal.
Concrete suggestions on the subject itself:
...
none of that is on-topic for the draft being considered on-thread.
Having said all that, I still am in favor of preventing UDP
fragmentation, regardless of the MTU used, and support this draft.
