DNS Validator

The DNS Validator analyzes a domain's DNS footprint across critical record types, verifying that A, AAAA, MX, CNAME, and TXT records exist as intended. It queries authoritative servers and a selection of resolvers to detect discrepancies, such as missing records, mismatched values, or stale TTLs. By compiling per-record results into a health snapshot, it enables operators to confirm readiness before launch or migration, and to triage issues that would impact web hosting or mail deliverability.
The tool's core workflow is conceptually simple: you provide a domain and the record types you want validated, optionally supply expected values for automated comparison, and run the check. The validator performs authoritative lookups for each type, cross-checks results against expectations, and aggregates findings into a structured report. It also performs propagation checks by querying regional resolvers and measuring the time-to-visibility of updates, helping teams gauge whether changes have propagated globally.
Beneficiaries include system administrators, DevOps engineers, MSPs, and IT admins responsible for domain migrations, uptime guarantees, or email deliverability. Unique value lies in the combination of authoritative accuracy, cross-resolver propagation insight, and automation-friendly outputs suitable for integration with CI pipelines. Use cases cover new domain setup, DNS migrations, SPF/DKIM/TXT alignment, or post-change validation. Outputs include a clear health score, record-by-record statuses, and remediation guidance to expedite fixes.
