Hi Tommy - A quick clarification in enumeration 1 in section 1 (Introduction). The enumeration 1 says:

When only an IP address of an Unencrypted Resolver is known, the client queries a special use domain name to discover DNS SVCB records associated with the Unencrypted Resolver

Above did you mean "encrypted" instead of "Unencrypted" Resolver....?

Thanks
Sanjay

Hey everyone,

We have posted an update to DDR and welcome additional review. Many thanks to everyone who has reviewed so far. We are hoping to get additional feedback as we rev a -02 ahead of the deadline for IETF 111.

This version addresses some feedback regarding the use of IPv4/IPv6 examples, the use of IP hints, and some clarity of language regarding terminology ("equivalence" versus "designation") and scope.

I would like to highlight for the benefit of some feedback regarding scope that the scope of this draft remains limited in nature. For example, DDR has not and still does not attempt to solve the "85%" problem. You will see commentary on the GitHub bugs following that scoping.

Thanks,
Tommy

> Abstract:
>    This document defines Discovery of Designated Resolvers (DDR), a
>    mechanism for DNS clients to use DNS records to discover a resolver's
>    encrypted DNS configuration.  This mechanism can be used to move from
>    unencrypted DNS to encrypted DNS when only the IP address of an
>    encrypted resolver is known.  It can also be used to discover support
>    for encrypted DNS protocols when the name of an encrypted resolver is
>    known.  This mechanism is designed to be limited to cases where
>    unencrypted resolvers and their designated resolvers are operated by
>    the same entity or cooperating entities.
