DNSSEC Test

Check whether DNS Security Extensions are enabled for a domain.

What is DNSSEC?

Domain Name System Security Extensions (DNSSEC) is a suite of security protocols that adds cryptographic signatures to DNS records. It ensures that the DNS responses received by a user's browser have not been altered in transit. Without DNSSEC, attackers can manipulate DNS responses to redirect traffic to other websites.

Use the Geekflare tool to confirm that DNSSEC is configured on your domains. Misconfigured DNSSEC can cause a domain to become completely inaccessible, as validating DNS resolvers will reject queries with broken or expired signatures. This tool helps you verify the integrity of your chain of trust before configuration errors impact your users.

Key DNSSEC Records Analyzed

CheckWhy It Matters
DNSSEC statusShows whether DNSSEC records were returned for the domain.
DNSKEY recordsDNSKEY records publish the public keys used to validate signed DNS data.
RRSIG recordsRRSIG records contain signatures over DNS record sets.
Algorithms and key tagsThese values help identify which signing keys and algorithms are in use.

How to Read the Results

If DNSSEC is Enabled, the domain returned DNSSEC records such as DNSKEY or RRSIG.

If DNSSEC is Disabled, the domain did not return DNSSEC records in this check. To enable DNSSEC, configure signing at your DNS provider, publish the right DS record, and verify the chain of trust after propagation.

DNSSEC validates DNS authenticity and integrity. It does not encrypt DNS queries or hide which domain is being resolved.
