Ballot Text

Technical Summary

   This document describes an EDNS(0) option that can be used by DNS
   Update requestors and DNS servers to include a lease lifetime in a
   DNS Update or response, allowing a server to garbage collect stale
   resource records that have been added by DNS Updates

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 Matter (part of
CSA) and that brought in vocal participants and implementers. The draft in its
current shape represents the broad agreement of these folks.

None in the WG. Apple have used this since 2005 but didn't seek standardisation
at the time. They brought it to the WG at IETF111 as it's a component of SRP.
There was brief debate about whether it should sit in DNSSD. It was discussed
with DNSOP chairs and agreed to call for adoption into DNSSD. The adoption call
went to both groups, but there was no pushback.

The WG chairs have obtained reviews from multiple individuals involved with Matter. They
support publication of the draft. No directorate reviews requested by the WG chairs but
a detailed DNS directorate was performed during IETF Last Call.

Document Quality

The doc shepherd is aware of at least two implementations already in production or going into
production soon, with more to come after publication. It is a mandatory part of
the Matter spec, so implementations are likely to expand greatly over the next
few years.

Personnel

   The Document Shepherd for this document is Chris Box. The Responsible
   Area Director is Éric Vyncke.
