How to use this tool
Choose the resolver and record scope. Results compare local DNS with Cloudflare and Google, report resolver agreement and DNSSEC authentication, and can add external RapidAPI health, DNSSEC, and resolver intelligence.
Result transparency
Every report identifies completed data sources, unavailable providers, individual findings, coverage, and detailed evidence. Unavailable checks are excluded from scoring rather than treated as passing.

Audit DNS records, resolver agreement, delegation, and DNSSEC signals with local, public, and optional RapidAPI sources.
What should I enter in the
Enter the domain or hostname requested by the form without unrelated text, paths, or multiple values.
Are the results live?
The result reflects the data and network response available when the check runs. DNS, HTTP, and certificate information can change later.
What does an unavailable result mean?
An unavailable result means the requested source could not be reached or did not return usable data. It is not automatically a pass or a failure.
Should I rely on this result alone before making changes?
Use the report as a diagnostic reference and confirm important changes with the authoritative provider, hosting panel, or certificate issuer.
