How do we encode 'question received over QUIC'? Discussion split from #9:
Habbie: In related news there is no way for us to currently indicate that the query came in over QUIC and we should probably do something about that..
rgacogne: Since we have the original destination port, it should be possible to use that to infer whether the query was received over TLS (port 853) or QUIC (port TBD AFAIK).
Habbie: the QUIC port could be 80 or 443 as far as I know, but perhaps that's good enough, yes. But what do we put in the protocol field then? UDP?
raybellis: QUIC is a pseudo-L4 protocol, which is currently encoded by the 8-bit
"protocol" field but for which no defined value exists in the IANA
protocol registry.
Nor does QUIC exist in the AF registry (since it uses IP for its L3
protocol). Arguably a meta-value should be defined in the protocol
registry that wouldn't be used on-the-wire (because QUIC uses UDP) but
might be used to otherwise indicate that QUIC had been used ?
Habbie: Yes, indeed. Shall I take this question to quic@ietf?
