DNSSEC checker

DNSSEC cryptographically signs your DNS records so a recipient can confirm they came from you and weren't tampered with in transit. We verify the structural chain (DS records at the parent, DNSKEY at the child, RRSIG signatures), check the signing algorithm, and ask a validating recursive resolver whether the AD (authenticated-data) bit comes back set. SMB security audits frequently ask for this evidence.

Example result for example.com

Sample data. Run the check above to see yours.

DNSSEC not enabled

Not set

example.com has no DS record in the parent zone, so its DNS answers are not signed.

  • Turn on signing at your DNS host, then publish the DS record at your registrar.
