DMARC Record Checker

Find the DMARC policy that tells receiving servers how to handle authentication failures.

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 DMARC Record Checker

DMARC Record Checker is a focused network utility for administrators, developers, support teams and people troubleshooting an internet connection. Find the DMARC policy used for email authentication failures and reporting.

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.
