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, which is now RFC8490.
The documents is of good quality. There currently is some non-published
implementations. The reviews on this document were vigorous and thorough.
Document Shepherd is Tim Wicinski.
Area Director is Éric Vyncke.
New entries to be added in two existing registries.
