What this ranking shows
Datacenter proxies originate from hosting and cloud address space rather than consumer access networks. Their concentration and automation-friendly infrastructure make ASN-level visibility useful for security operations.
Networks are ranked by unique proxy IPs observed during the last 31 days. Supporting metrics show repeat observations, geographic diversity, persistence, and the day-by-day footprint of each ASN.
Hosting providers serve many legitimate customers alongside proxy operators and compromised workloads. The ranking describes observed infrastructure and should be combined with endpoint-level evidence when making policy decisions.
