DNSSEC Checker

Check whether a public DNS answer validates with DNSSEC using the resolver's authenticated-data result.

This live lookup sends only the IP address or hostname you enter to the named public lookup service. Do not submit private hostnames or confidential infrastructure details.

About the DNSSEC Checker

DNSSEC Checker is a focused network utility for administrators, developers, support teams and people troubleshooting an internet connection. Check whether a public DNS answer is authenticated through DNSSEC.

Live results use a public lookup service. Only the address or hostname submitted for lookup is sent to that service.

Results describe public network information and should not be treated as proof of a person's identity or exact physical location.
