This document defines Discovery of Designated Resolvers (DDR), a set
of mechanisms for DNS clients to use DNS records to discover a
resolver's encrypted DNS configuration. An Encrypted DNS Resolver
discovered in this manner is referred to as a "Designated Resolver".
These mechanisms can be used to move from unencrypted DNS to
encrypted DNS when only the IP address of a resolver is known. These
mechanisms are designed to be limited to cases where Unencrypted DNS
Resolvers and their Designated Resolvers are operated by the same
entity or cooperating entities. It can also be used to discover
support for encrypted DNS protocols when the name of an Encrypted DNS
Resolver is known.
This document is a product of the Adaptive DNS Discovery Working Group of the
IETF.
This is now a Proposed Standard.
