Free IP tool
Most proxy traffic originates from cloud and hosting networks. Flag datacenter proxies by IP with ASN-aware detection and a confidence score.
Overview
Datacenter proxies run on servers in hosting and cloud providers rather than on home connections. They are cheap and fast, which makes them the most common source of automated and abusive traffic. Datacenter proxy detection identifies IPs that belong to hosting ASNs and known proxy infrastructure, so you can separate genuine residential visitors from server-originated requests.
Signals
Hosting origin is the strongest signal, we enrich it with reputation.
Classifies IPs owned by cloud and hosting providers worldwide.
Matches against ranges sold by commercial datacenter proxy services.
Identifies AWS, GCP, Azure and other cloud egress IPs.
Past abuse from the range raises the score.
Clear flag that an IP is not a consumer ISP connection.
A 0–100 value so you can allow legitimate server traffic where needed.
API

Use cases
Block high-volume scraping from cloud servers.
Stop disposable accounts created from hosting IPs.
Apply stricter limits to datacenter-origin traffic.
Exclude server traffic from human-visitor metrics.
