Treat this document as a focused evidence review: Publish AAAA and IP6.ARPA data as separate forward and reverse decisions. Only the official source and traced locations below supply facts. Confirm applicability before acting.

\n

Source fact:

\n

The official RFC 3596 — DNS Extensions to Support IP Version 6 from RFC Editor / Internet Engineering Task Force supports the following bounded statements:

\n\n

Only the traced statements above are asserted as source facts. Apply the review to authoritative zones, delegations, resolvers, caches, record owners, and the clients that consume the resulting answers after confirming that the source and deployed context match.

\n

What the source does not establish

\n

This RFC evidence supports only the named DNS protocol decision; it does not prove Windows implementation support or a safe production configuration. No current deployment state or change approval follows from the source alone. Validate Windows DNS roles, Active Directory-integrated data, forwarding paths, time, routing, firewalls, and registrar or registry state, and treat examples or options as conditional inputs rather than defaults.

\n

Applicability questions

\n\n

DSE recommendation:

\n

DSE recommends using the cited source as the evidence anchor for this decision. Begin by recording scope and current state before deciding whether a change is warranted. Record the source location, examined part of authoritative zones, delegations, resolvers, caches, record owners, and the clients that consume the resulting answers, observed and expected states, owner, and reason for deviation.

\n

Translate the conclusion into change control only after documenting dependencies, impact, test method, expected signals, failure signals, and restoration steps. Include Windows DNS roles, Active Directory-integrated data, forwarding paths, time, routing, firewalls, and registrar or registry state, while excluding secrets and sensitive personal or topology data from ordinary tickets.

\n

Verification and evidence

\n

Build a reproducible chain from Section 2.1 (Format); Section 2.3 (AAAA Query); Section 2.5 (IP6.ARPA Domain) to the observed environment. Useful domain evidence includes zone data, packet captures, query transcripts, delegation checks, resolver configuration, and negative-answer behavior; label every item with scope, timestamp, collector, and stable identifier.

\n

Close the review only when the evidence, exception handling, resulting action, and after-state are linked. Schedule a new review after material technical, organizational, incident, or source changes; today’s observation is not a continuing guarantee.
