When to use it

Use a DNSSEC check when validating whether a domain has signed DNS records and whether the expected DNSSEC-related records are visible publicly.

What to inspect

DS records connect the parent zone to the child zone, DNSKEY records publish signing keys, RRSIG records carry signatures, and NSEC or related records support authenticated denial of existence.

How to interpret missing records

Missing DNSSEC records can mean DNSSEC is not enabled, only partially configured, or not visible from the resolver path being queried. Compare registrar settings and authoritative DNS output.
