Of the 60,484 IP addresses ffraud has observed in Cloudflare, Inc. (AS13335), 33,146 — 55% — are flagged as abusive. That is an extraordinarily high concentration. Ordinary end-user networks sit in the low single digits. On a dedicated hosting network a rate this high is the classic bulletproof-hosting or proxy-operation signature, where abuse is the business model. On a large shared platform or CDN it instead reflects abusive tenants riding otherwise-legitimate infrastructure. Either way, unfiltered traffic from this network carries real risk.

How does ffraud measure this?+
The rate is the share of Cloudflare, Inc.'s IPs that ffraud has independently confirmed as abusive, each verified at least twice by our honeypot sensors and community reports. It is a measurement of observed traffic, not a legal judgment of the operator. See how we score at https://ffraud.com/docs/methodology.
