Reading this verdict
The verdict combines ASN classification, registry allocation, cloud provider ranges, proxy/Tor listings, and live threat feeds — methodology here. Confidence reflects how many independent signals agree. A residential verdict with a high risk score means the address is real ISP space but appears in abuse feeds — what that means.
