DNSSEC (Domain Name System Security Extensions) helps ensure that the response you get from a DNS lookup is authentic and has not been tampered with.
This tool attempts to retrieve the DNSKEY records for the domain. If DNSSEC is enabled, you should see one or more DNSKEY records, which look similar to cryptographic key data.
Why DNSSEC Matters:
- Security: DNSSEC prevents attackers from redirecting users to malicious sites by verifying DNS response authenticity.
- Trust: Domains with DNSSEC enabled are less vulnerable to spoofing.
- Compliance: Some regulatory or industry standards now recommend (or require) DNSSEC for additional security.
When DNSSEC Might Not Be Enabled:
If no DNSKEY records are returned, the domain likely doesn’t have DNSSEC enabled. This doesn’t always imply a problem, but enabling DNSSEC is considered a good security practice.
Example Output:
If you see records like the example above, DNSSEC is enabled. Otherwise, the tool may display an error or note the absence of DNSKEY records.
