How privacy works
Private lookups are not added to public searches, stored reports or change history. This does not remove a report that was already public. Your choice lasts for this browser session.

What needs attention
Prioritized observations from this check. Review changes with whoever manages the website.
- Review
No DMARC record was found at this domain
A DMARC policy was not returned by this check. Parent-domain policy discovery and message authentication were not tested.
Next step: Check whether a parent policy applies; otherwise configure DMARC reporting, verify SPF/DKIM alignment, then choose an appropriate policy.
- Improve
Review browser security headers
Content-Security-Policy did not meet the conservative header checks. This is not a complete security audit.
Next step: Review these headers with the site developer and test policy changes before enforcing them.
- Good to know
Only the network operator is identified
The visible IP network is known, but no hosting-specific evidence confirms the company or reseller serving the site.
Next step: Use the evidence as a network attribution and verify the hosting provider with the website owner if needed.
Evidence by layer
The company operating a network and the company selling the hosting can be different.
Network operators
IONOS
Network ownership alone does not confirm the retail hosting provider.
