Dangling DNS Check
Find expired and unregistered domains your DNS still trusts: in SPF includes, DMARC reporting addresses, NS and MX records, CNAMEs and certificate records. Verify an email at your domain to run the scan.

Why This Matters
Domains expire quietly. DNS records that reference them don’t. We registered an expired DMARC reporting domain for $10 and started receiving reports for 86 organizations, including a NYSE-listed company and two US county governments. This tool finds the same kind of gap in your own DNS before someone else does.
