Frequently Asked Questions

Find Quick Answers

What is DNSSEC and why is it important?

DNSSEC (Domain Name System Security Extensions) adds cryptographic signatures to DNS records to prevent DNS spoofing and cache poisoning attacks. It ensures that DNS responses are authentic and haven't been tampered with.

What types of DNSSEC records does this tool analyze?

The tool analyzes DS (Delegation Signer), DNSKEY (DNS Key), RRSIG (Resource Record Signature), and NSEC/NSEC3 (Next Secure) records to validate the complete DNSSEC chain of trust.

Can I analyze multiple domains at once?

Currently, the tool analyzes one domain at a time. For batch analysis, you can upload a zone file containing multiple domain records.

Does this tool modify my DNS configuration?

No, this is a read-only analysis tool. It only queries and validates existing DNSSEC records without making any changes to your DNS configuration.
