Residential proxies look like real home users, that is the point. Our detection uses network reputation and pool intelligence to flag them anyway.
Overview
Residential proxies route traffic through real consumer devices and ISP ranges, making automated and fraudulent traffic look like an ordinary home user. Because the IP belongs to a legitimate ISP, simple ASN or datacenter checks miss them. Residential proxy detection identifies IPs that are part of a residential proxy network using behavioural reputation, pool membership and shared-usage patterns rather than ownership alone.
Signals
These proxies hide in ISP space, so detection leans on reputation, not just ASN.
Cross-references IPs against known residential proxy provider pools.
A single home IP serving many unrelated sessions is a red flag.
How the address has behaved across our lookup network over time.
Rapid IP rotation within an ISP range typical of proxy services.
Combines ISP ownership with anomaly signals to avoid false positives on real users.
A 0–100 score lets you treat likely vs. certain proxies differently.
