Updates to Locally Served DNS Zones and IP Special-Purpose Address Space Registries

Introduction "Locally Served DNS Zones", it defines two IANA registries called "IPv4 Locally-Served DNS Zone" and "IPv6 Locally-Served DNS Zone" registries. This document changes the registration policy for that registry from "IETF Review" to "Expert Review". Also, this document updates IP Special-Purpose Address Space registries to indicate whether an IP address block is eligible to be in Locally-Served DNS Zones. This change is meant to ensure consistent registrations between the above registries and future failures to make appropriate registrations in "IPv6 Locally-Served DNS Zone" such as in .

Terminology 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 when, and only when, they appear in all capitals, as shown here. DNS terminology is as described in .

Updates to RFC 6063 Please update "IANA Considerations" as follows: OLD:

This registry can be amended through "IETF Review" as per . As part of this review process, it should be noted that once a zone is added it is effectively added permanently; once an address range starts being configured as a local zone in systems on the Internet, it will be impossible to reverse those changes.

NEW:

This registry can be amended through "Expert Review" policy (). As part of this review process, it should be noted that once a zone is added it is effectively added permanently; once an address range starts being configured as a local zone in systems on the Internet, it will be impossible to reverse those changes. More guidance for Designated Experts is provided in guidance of THIS_DOCUMENT.

Guidance for Designated Experts In changing the approval to "Expert Review", there should be some additional guidance. Here are some examples (not all mandatory) on what the Reviewer should look for:

Should have at least an internet-draft written which can explain the usage.
The various Working Groups in the IETF should have input the decision process. This will be at least DNSOP and V6OPS, but will also include others. The list should not be limited but vetted by the Area Directors.

Changes to the IPv6 Locally-Served DNS Zones Registry IANA is requested to add the zones listed below to the "IPv6 Locally-Served DNS Zone" registry: TBC with entries.

Changes to the IP Special-Purpose Space Registries

Eligible to Locally-Served DNS Zones New Column IANA is requested to add a new column, Eligible to Locally-Served DNS Zones, to the "IPv6 Special-Purpose Address Space" and "IPv4 Special-Purpose Address Space" registries.

Eligible to Locally-Served DNS Zones Note IANA is requested to add the following note to the "IPv6 Special-Purpose Address Space" and "IPv4 Special-Purpose Address Space" registries:

Eligible to Locally-Served DNS Zones:: A boolean value indicating whether the IP address block is to be added to the Locally-Served DNS Zones IANA registry.

IPv6 Locally-Served DNS Zone Registry Note IANA is requested to add the following note to the "IPv6 Special-Purpose Address Space" registry:

Note:: IANA has to add relevant entries for "Eligible to Locally-Served DNS Zones" set to "True" in the IPv6 Locally-Served DNS Zone Registry.

IPv4 Locally-Served DNS Zone Registry Note IANA is requested to add the following note to the "IPv4 Special-Purpose Address Space" registry:

Note:: IANA has to add relevant entries for "Eligible to Locally-Served DNS Zones" set to "True" in the IPv4 Locally-Served DNS Zone Registry.

Initial IPv6 Locally-Served DNS Zone Registry TBC.

Initial IPv4 Locally-Served DNS Zone Registry TBC.

Operational Considerations TBC.

Security Considerations This document does not add new security risks other than those already discussed in [, , and .
