DNS Report (Phase 2)

DNS Report builds a broader health snapshot for a domain, combining record sanity, delegation hints, and risk-oriented interpretation into a single troubleshooting view.

What this tool checks

Core record-set completeness for operational DNS baselines.
Delegation and authority signals that can destabilize downstream services.
Consolidated summary designed for incident briefings and handover notes.

How to read the output

Result Summary is useful for deciding whether DNS is likely root cause.
Overview highlights highest-impact record or authority anomalies first.
Technical Details supports deep review during major migration or outage events.
Raw Output enables consistent evidence sharing across teams.

Common failure patterns

Incomplete baseline records for domain services (mail, web, validation).
Delegation drift between registrar and authoritative provider.
Weak or inconsistent policy records increase operational risk.
Legacy zone data remains after infrastructure consolidation.

Remediation workflow

Align expected DNS baseline with current production architecture.
Correct authority chain issues before editing downstream record details.
Remove obsolete records to reduce ambiguity and support burden.
Re-run report after each controlled DNS change set.

FAQ

How is DNS Report different from NsLookup?

NsLookup is query-specific; DNS Report is a broader health summary across important DNS controls.

Can report warnings be ignored if users are unaffected?

Short term maybe, but unresolved DNS risk frequently becomes user-visible during later changes.

Does report output replace manual DNS review?

No. It accelerates review, but critical changes still require expert validation.

Should I run this after every DNS deployment?

Yes, especially for domains supporting customer-facing or security-sensitive services.

Can this report help with postmortems?

Yes. It gives structured snapshots useful for timeline and root-cause narratives.
