The certificate names above were validated by the issuing authority at issuance. They describe the certificate, not conduct by the names' owner — a legitimately issued certificate can be deployed on a listed host by whoever holds its private key, so treat the name as a pivot to investigate rather than as an attribution.

Neighbourhood · 45.136.14.0/24 · 1 host

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