Treat this document as a focused evidence review: Require transparent DNS proxy behavior through broadband gateways. Only the official source and traced locations below supply facts. Confirm applicability before acting.
\nThe official RFC 5625 — DNS Proxy Implementation Guidelines from RFC Editor / Internet Engineering Task Force supports the following bounded statements:
\nKeep the evidence boundary at these traced claims. They support a review of authoritative zones, delegations, resolvers, caches, record owners, and the clients that consume the resulting answers; they do not support conclusions outside the source’s stated conditions.
\nThis 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.
\nDSE recommends using the cited source as the evidence anchor for this decision. Anchor the review in the cited section and keep observation separate from interpretation. 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.
\nTranslate 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.
\nKeep the source locations Section 3 (The Transparency Principle); Sections 4.1 (Unexpected Flags and Data), 4.2 (Label Compression), and 4.3 (Unknown Resource Record Types); Section 4.4 (Packet Size Limits) adjacent to the sanitized artifacts used for comparison. Prefer zone data, packet captures, query transcripts, delegation checks, resolver configuration, and negative-answer behavior, with enough identity and timing data for an independent recheck.
\nRecord the decision even when no change is made, including uncertainty and the next trigger. Use safe testing conditions for disruptive work, preserve rollback proof, and revisit the conclusion after relevant platform, dependency, vendor, or ownership changes.
