Hello dnsop,
Another draft, unrelated to my feelings for Classic DNS over UDP.
David, John, and I wrote this draft which defines a way to associate IP
prefixes with a domain name. This is somewhat reminiscent of the
experimental APL record (RFC 3123) with more specific structure and intent.
The basic idea is there are services identified by a domain name that
trigger network traffic being sent to IP addresses other than those in
existing DNS RR types. A common example is the use of WebRTC by a
program that uses teleconferencing[.]vendor[.]example for initial
connections, but ends up streaming to IP addresses not discovered via
the DNS. QUIC also supports servers migrating clients to preferred IP
addresses which may not be present in the DNS. Such vendors tend to
document their required IP prefixes for firewall configuration purposes,
but this leads to manual labor by sysadmins to accumulate these,
possibly with vendor lock-in mechanisms.
This document intends to make that process automatic: instead of
tracking separate vendor's documentation or APIs, accumulation of
addresses associated with a service is via DNS queries for the vendor's
domain names, which do not tend to change frequently.
Thanks,
Tommy

Abstract:
RFC9000 defines a mechanism that allows servers to migrate clients to
another IP address without name resolution. The new address may not
be discoverable as A/AAAA records for that domain name. This draft
defines a mechanism that allows a client to get advance notice of
associated IP addresses for a domain name as part of the DNS query.
