No audit yet
Enter a domain to audit delegation, nameservers, SOA, mail, DNSSEC, and security records.
How This Query Works
The health check audits the full DNS setup of a domain, from parent delegation down to security records, and scores each area.
Delegation consistency compares NS records served by the parent with those in the zone itself.
Mail checks verify MX hosts resolve and that SPF and DMARC policies exist.
DNSSEC, CAA, and HTTPS records are graded so misconfigurations stand out at a glance.
