Abstract:
Changes in CDS/CDNSKEY, CSYNC, and other records related to
delegation maintenance are usually detected through scheduled scans
run by the consuming party (e.g. top-level domain registry),
incurring an uncomfortable trade-off between scanning cost and update
latency.
A similar problem exists when scheduling zone transfers, and has been
solved using the well-known DNS NOTIFY mechanism ([RFC1996]). This
mechanism enables a primary nameserver to proactively inform
secondaries about zone changes, allowing the secondary to initiate an
ad-hoc transfer independently of when the next SOA check would be
due.
This document extends the use of DNS NOTIFY beyond conventional zone
transfer hints, bringing the benefits of ad-hoc notifications to DNS
delegation maintenance in general. Use cases include DNSSEC key
rollovers hints via NOTIFY(CDS) and NOTIFY(DNSKEY) messages, and
quicker changes to a delegation's NS record set via NOTIFY(CSYNC)
messages.
Furthermore, this document proposes a new DNS record type,
tentatively referred to as "NOTIFY record", which is used to publish
details about where generalized notifications should be sent.
