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.

Shared TLS certificate · 1 host

These hosts served the same certificate. That is the strongest link this corpus can draw between two addresses, though it evidences a shared BUILD rather than a shared operator: a leaked or resold profile puts the same certificate in different hands. Full cohort →

Shared JA4X issuance template · 20 hosts

These hosts issued certificates from the same template — the same distinguished-name fields hashed in the same order. It links tooling, not necessarily an operator. Full cohort →

Neighbourhood · 91.92.241.0/24 · 2 hosts

2 other confirmed hosts in the same /24. Adjacent addresses under one operator are a different signal from a shared certificate — they suggest a block, not a build.
