Do you flag legitimate cloud services?

We report the hosting verdict with a score and ASN details, so you can allowlist known good services while blocking abusive ones.

Which endpoint returns this?

GET /v1/proxy/{ip} returns the proxy type including datacenter, plus ASN data via /v1/asn/{ip}.

Is there a free tier?

Yes — 100 lookups per month free.

Datacenter Proxy Detection

Most proxy traffic originates from cloud and hosting networks. Flag datacenter proxies by IP with ASN-aware detection and a confidence score.

Overview

What is datacenter proxy detection?

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

How datacenter proxy detection works

Hosting origin is the strongest signal — we enrich it with reputation.

Hosting ASN mapping

Classifies IPs owned by cloud and hosting providers worldwide.

Known proxy infrastructure

Matches against ranges sold by commercial datacenter proxy services.

Cloud provider ranges

Identifies AWS, GCP, Azure and other cloud egress IPs.

Reputation history

Past abuse from the range raises the score.

Non-residential signal

Clear flag that an IP is not a consumer ISP connection.

Confidence score

A 0–100 value so you can allow legitimate server traffic where needed.

Use cases

Where teams use it

Scraping defense

Block high-volume scraping from cloud servers.

Signup abuse

Stop disposable accounts created from hosting IPs.

Rate-limit tuning

Apply stricter limits to datacenter-origin traffic.

Analytics hygiene

Exclude server traffic from human-visitor metrics.

FAQ

Frequently asked questions

Datacenter proxies run on hosting/cloud servers and are detectable by ASN. Residential proxies use real ISP IPs and need reputation-based detection.
