The certificate names above are what the certificate ASSERTS, not proof this host owns them — a self-signed certificate can claim any subject, so treat a familiar name here as an impersonation attempt rather than an identity.

Listed in error?

This page is generated from automated scanning and is publicly available. If you are responsible for this address and it should not be listed, write to support@publicmosaic.com — see abuse & takedown for what we need and what happens next, or opt-out to exclude a whole range from scanning.

Addresses are frequently compromised third-party hosts rather than infrastructure their owner stood up. A listing records what a scan observed at a point in time; it is not an allegation about whoever pays for the address.
