Technical Summary

   This document specifies the "SVCB" and "HTTPS" DNS resource record
   (RR) types to facilitate the lookup of information needed to make
   connections to network services, such as for HTTPS origins.  SVCB
   records allow a service to be provided from multiple alternative
   endpoints, each with associated parameters (such as transport
   protocol configuration and keys for encrypting the TLS ClientHello).
   They also enable aliasing of apex domains, which is not possible with
   CNAME.  The HTTPS RR is a variation of SVCB for HTTPS and HTTP
   origins.  By providing more information to the client before it
   attempts to establish a connection, these records offer potential
   benefits to both performance and privacy.


Working Group Summary

Working group consensus was strong, though it was rough in spots.

During WGLC, discussions came up about the syntax of the records.  The issues raised about the syntax was discussed in depth, and the issues raised were very much the rare exception rather than the rule.

Document Quality

While these are updates to existing standards, there is an implementation section where several versions of open source software has implemented this.
