Technical Summary

   The Service Registration Protocol for DNS-Based Service Discovery
   uses the standard DNS Update mechanism to enable DNS-Based Service
   Discovery using only unicast packets.  This makes it possible to
   deploy DNS Service Discovery without multicast, which greatly
   improves scalability and improves performance on networks where
   multicast service is not an optimal choice, particularly IEEE 802.11
   (Wi-Fi) and IEEE 802.15.4 (IoT) networks.  DNS-SD Service
   registration uses public keys and SIG(0) to allow services to defend
   their registrations.

Working Group Summary

Broad agreement. DNSSD has historically been a pretty small WG with a very small
number of vocal participants, but this draft is required for CHIP/Matter (another
SDO in the home space) and that brought in vocal participants and implementers.
The draft in its current shape represents the broad agreement of these folks.

Document Quality

The I-D shepherd is aware of at least two implementations already in production or going into
production soon, with more to come after publication.

There have been detailed reviews by directorates as well as reviews from multiple individuals involved with Matter. They
support publication of the draft.


   The Document Shepherd for this document is David Schinazi. The
   Responsible Area Director is Éric Vyncke.


  IANA #1273917 IANA has reviewed all actions in agreement with the authors.
