Internet-Draft catalog-zone-xfr-properties March 2025
1. Introduction
DNS Catalog Zones [RFC9432] described a method for automatic DNS zone
provisioning among DNS name servers by the catalog of zones to be
provisioned as one or more regular DNS zones. Configuration
associated with the member zones, such as from which primary name
servers and with which TSIG keys [RFC8945] to transfer the zones, and
from which IP addresses and with which TSIG keys DNS notifies
[RFC1996] are allowed, were assumed to be preprovisioned at the
catalog consumer.
This document specifies DNS Catalog Zones Properties to specify
primary name servers and TSIG keys to use to transfer the member
zones in a catalog, as well as properties to specify which IP
addresses, using which TSIG keys, are allowed to notify [RFC1996] the
secondary name server serving the member zones, in order to remove
the need to preprovision those at the catalog consumers.
1.1. Requirements language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
2. Description
Body text [REPLACE]
3. Catalog Zone Structure
These new properties can be at the top of the catalog zone, where
they will affect all member zones, or under a member zone label,
where they will affect just that member zone.

Zones Properties" registry under the "Domain Name System (DNS)
Parameters" page:
