Technical Summary

This document describes the use of TLS to provide privacy for DNS. In addition, this document specifies two usage profiles for DNS-over-TLS and provides advice on performance considerations to minimize overhead from using TCP and TLS with DNS.

Working Group Summary

This document was heavily reviewed and discussed int the working group, and the community is strongly behind this document.  The authors made sure that all issues raised during the process were addressed.  Additionally, there is a complementary design moving through the working group (draft-ietf-dprive-dnsodtls), and both sets of authors worked together to ensure the issues raised between the drafts were resolved.  Both groups of authors have worked exceptionally well together.

Document Quality

This is a well structured document with several vendors signalling intent to implement and support. A current implementation is offered from NLNetLabs (unbound).
The workgroup performed well in bringing forth this document. The draft lists 6 authors, and the AD is in support of that number, a note has already been sent to the RFC-Editor.
