How to use this tool
Enter two different domains. The report compares address, nameserver, mail exchanger, TLS issuer, and redirect evidence. Its score represents technical overlap only and is not proof of common ownership.
Result transparency
Every report identifies completed data sources, unavailable providers, individual findings, coverage, and detailed evidence. Unavailable checks are excluded from scoring rather than treated as passing.
Frequently Asked Questions
What does the Domain Relationship Analyzer check?
Compare two domains for shared DNS, mail, TLS, and redirect infrastructure using transparent weighted evidence.
What should I enter in the
Enter the domain or hostname requested by the form without unrelated text, paths, or multiple values.
Are the results live?
The result reflects the data and network response available when the check runs. DNS, HTTP, and certificate information can change later.
What does an unavailable result mean?
An unavailable result means the requested source could not be reached or did not return usable data. It is not automatically a pass or a failure.
Should I rely on this result alone before making changes?
Use the report as a diagnostic reference and confirm important changes with the authoritative provider, hosting panel, or certificate issuer.
