Hi All, 

This update attempts to address the comments we received in IETF Last Call (thanks to all that provided comments):

* Return RFC 8467 to a normative reference after more discussion on padding policies
* Update details of text on port allocation of 853 after discussion with IANA
* Update to security considerations with additional references and text on recursive to auth, zone transfer and general DNS/QUIC security.
* Clarify text on stream usage
* Various typos fixed

Note that we tried to address the Secdir review via this PR which contains some discussion of the points raised: https://github.com/huitema/dnsoquic/pull/145. If there are additional changes needed for this review please let us know by providing text (a PR or new issue in the same repo is welcome). 

Best regards

Sara.

> Abstract:
>   This document describes the use of QUIC to provide transport privacy
>   for DNS.  The encryption provided by QUIC has similar properties to
>   that provided by TLS, while QUIC transport eliminates the head-of-
>   line blocking issues inherent with TCP and provides more efficient
>   packet loss recovery than UDP.  DNS over QUIC (DoQ) has privacy
>   properties similar to DNS over TLS (DoT) specified in RFC7858, and
>   latency characteristics similar to classic DNS over UDP.  This
>   specification describes the use of DNS over QUIC as a general-purpose
>   transport for DNS and includes the use of DNS over QUIC for stub to
>   recursive, recursive to authoritative, and zone transfer scenarios.
