VPN Detection

Free IP VPN Lookup Tool

Need to check if an IP address is hiding behind a VPN? You’re in the right place. Run a quick VPN detection test and find out if that IP has been used to tunnel traffic through a VPN, proxy, or anonymizer.

Our detection engine is built for accuracy — 99.9% effective at spotting VPN IPs across IPv4 and IPv6 ranges.

Protect Your Platform from Proxies, VPNs & TOR In Real Time

Fraudo.io’s VPN Detection API gives you instant insights into risky traffic. Whether you’re running an eCommerce site, SaaS product, or ad platform, you can spot and block anonymized connections before they harm your platform.

No complicated setup, just fast, accurate results.

Add VPN Detection to Your Website in Minutes

Spotting a VPN is just the beginning. A lot of abusive traffic also comes from data centers, proxy services, and Tor relays.

That’s where our proxy and VPN detection system comes in. You can run one-off lookups for suspicious IPs, monitor traffic live with our API, or bulk check lists using CSV uploads.

Covers All Countries, All Devices — IPv4 & IPv6

Our system flags both public and private VPN servers worldwide, including cloud-hosted VPNs from providers like NordVPN, ExpressVPN, ProtonVPN, Private Internet Access, Surfshark, and hundreds more.

Whether it's a shared VPN node or a private server, we’ll tell you exactly what you're dealing with.

What Is a VPN, Really?

A Virtual Private Network (VPN) creates a secure, encrypted connection between your device and the internet. It hides your data from ISPs, governments, and websites you visit.

It’s great for privacy, but also perfect for hiding behind fake locations or masked IP addresses.

Why Do People Use VPNs?

VPNs aren’t always bad. Businesses use them to give remote workers secure access to internal systems. In censored regions, people rely on VPNs to access basic online services.

But the same privacy cloak can also be used for fraud — fake signups, ad fraud, carding, phishing, and more.

Are VPN Users Always a Risk?

Not always. But when fraudsters want to stay hidden, VPNs are usually their first stop.

That’s why our detection tools go beyond a simple yes or no. We provide context — known VPN servers, risk history, and how often the IP is linked to abusive behavior.

How Does VPN Detection Work?

You send us an IP. We check it against our constantly updated threat network.

We determine whether it’s a VPN, proxy, or Tor exit node and assign a risk level based on behavior patterns, hosting provider analysis, abuse reports, and anonymity signals.

You can access this via our dashboard or integrate directly with our VPN Detection API.
