Charter for Working Group
This working group will standardize encodings for DNS queries and responses
that are suitable for use in HTTPS. This will enable the domain name system to
function over certain paths where existing DNS methods (UDP, TLS [RFC 7857],
and DTLS [RFC 8094]) experience problems.
The working group will re-use HTTPS methods, error codes, and other semantics
to the greatest extent possible. The use of HTTPS and its existing PKI
provides integrity and confidentiality, and it also allows interoperation
with common HTTPS infrastructure and policy.
The primary focus of this working group is to develop a mechanism that
provides confidentiality and connectivity between DNS clients (e.g., operating
system stub resolvers) and recursive resolvers. While access to
the primary use case for this work, precluding the ability to do so would
require additional preventative design. The working group will not engage in
such preventative design.
The working group will analyze the security and privacy issues that
could arise from accessing DNS over HTTPS. In particular, the working
group will consider the interaction of DNS and HTTP caching.
The working group will coordinate with the DNSOP and INTAREA working groups
for input on DNS-over-HTTPS's impact on DNS operations and DNS semantics,
respectvely. In particular, DNSOP will be consulted for guidance on the
operational impacts that result from traditional host behaviors (i.e.,
stub-resolver to recursive-resolver interaction) being replaced with the
Specification of how DNS-formatted data may be used for use cases beyond
normal DNS queries is out of scope for the working group.
The working group may define mechanisms for discovery of DOH servers
similar to existing mechanisms for discovering other DNS servers if
the chairs determine that there is both sufficient interest and
working group consensus.
The working group will use draft-hoffman-dispatch-dns-over-https as input.
