Shepherd writeup

    This document is Standards Track.


Technical Summary

   The Domain Name System (DNS) was designed to return matching records
   efficiently for queries for data that is relatively static.  When
   those records change frequently, DNS is still efficient at returning
   the updated results when polled, as long as the polling rate is not
   too high.  But there exists no mechanism for a client to be
   asynchronously notified when these changes occur.  This document
   defines a mechanism for a client to be notified of such changes to
   DNS records, called DNS Push Notifications.

Working Group Summary

  The significant thing was the initial version of the draft had both protocols
  and process.  The decision was made after discussion with DNSOP, to split
  this work into a separate draft and the protocol work into
  draft-ietf-dnsop-session-signal, currently working its way through DNSOP.
