DNS Validator

Nameserver delegation validator

Check whether a live or proposed nameserver set answers authoritatively, serves a consistent NS set, passes DNSSEC expectations, and avoids obvious network layout mistakes.

Test setup

Use live mode to inspect the published delegation, or proposed mode to test a nameserver set before making changes.

Run a validation to see the scorecard

You’ll get a delegation score, a clear pass/fail verdict, counted checks for live publication quality, and a separate list of IANA-inspired improvements that are informative but not scored.
