Hi everyone,

The chairs of ADD, DPRIVE, and DNSOPS have scheduled a joint interim on the topic of Split-DNS for January 27, 2022 from 1700-1830 UTC.

This was originally announced on the ADD list back on Dec 20, but didn’t get a lot of attention like due to the holidays at the time (https://mailarchive.ietf.org/arch/msg/add/Jd3Tql9dLkYEBWrv5ifsMAU7M9g/)

Background:
---------------

This is a follow up to the discussion that has taken place in ADD around how to support discovery of encrypted DNS resolvers in Split-DNS environments.   That extended discussion in ADD current stands at:  (1) The ADD group showed that there was consensus that the problem of how to do discovery in Split-DNS environments was important for the group to work on;  (2) The ADD group currently does not have consensus on how it should be done.  (3) A number of discussion issues that are outside of the ADD Charter have been raised around requirements that can uniquely occur in split-DNS environments.

It is the intent to use this joint session to discuss such issues, and others as needed to better understand the requirements that need to be satisfied for a ADD discovery mechanism for Split-DNS environments.

Motivation:
--------------

  *   Split-DNS is widely used in Enterprise and Intuitional network operations and in VPN environments.
  *   Without a practical and acceptable standard on how to discover encrypted DNS resolvers it is likely that operators that make use of split-DNS will take it upon themselves to invent and deploy a wide variety of non-standardized discovery methods.   This will hamper any future standards that may be developed, and will impact users negatively since they will not have a standard discovery mechanism to make use of.
  *   The hope is that by discussing the security, privacy, and operational needs of discovery in Split-DNS environments that the ADD group can make progress toward documenting how to do it in a standard way

Purpose of the Joint Interim:
--------------------------------------

  *   To discuss the issues around discovery of encrypted DNS resolvers in a  Split-DNS environment.

What this Interim is NOT:
-----------------------------------

  *   This is not intended as a referendum on the use of split-DNS.
  *   This is not a workshop on how proposals of how to end the practice of Split-DNS or how to re-engineer networks that have it currently deployed.

Agenda
-----------

  *   Agenda and any Materials will be posted at:

https://datatracker.ietf.org/meeting/interim-2022-add-01/session/add

  *   The chairs of the 3 groups are working on the agenda for the Interim and plan on making it available well ahead of the 1-27-2022 Interim Meeting.

Thanks,
Glenn Deen on behalf of the ADD, DPrive, DNSOPS co-chairs
