Hi!we, the authors of draft-ietf-core-dns-over-coap, are planning to present on DNS over CoAP at the next core interim (and at IETF 117) again.
In preparation for that, there are still some things to do and discuss ahead:
Discussions on 'ALPN "coap" for DTLS' [1] and 'Using SVCB with OSCORE/EDHOC' [2] somewhat got stalled. For our document, I think we need at least confirmation or decline that the "coap" ALPN could be used for DTLS, SVCB for OSCORE/EDHOC, I think is out of scope at the moment anyways.
Furthermore, there is still an open question, if DoC can or should be translated at a CoAP-HTTP proxy to DoH. Namely, how the FETCH that DoC uses should be translated into the POST/GET of DoH [3].
And last but not least, is there further feedback we did not address yet or is there new feedback that you want us to address?
