What this tool does not do / Limits

This tool only checks the format of RRSIG and DNSKEY text you paste. It does not fetch a zone, does not verify signatures cryptographically, and cannot prove a domain validates.

Frequently asked questions

Does this validate my domain for real?

No. Real validation needs the live zone and its chain of trust. This tool only checks the format of pasted text.

What is checked?

That the expected fields are present and in order for RRSIG and DNSKEY records.
