The Proxy dataset lists IP ranges observed operating as proxies, from datacenter HTTP and SOCKS endpoints to residential proxy networks that rent out real-user connections.
Refreshed daily from active measurements and curated intelligence, it lets you spot users hiding their true origin before they reach checkout, signup or content gates.
