Shared JA4X issuance template · 27 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 · 136.0.213.0/24 · 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.
