How Does VPN and Proxy Detection Work?
Our VPN detection tool works by checking your current public IP address against comprehensive databases that catalog IP ranges belonging to known VPN providers, proxy services, Tor exit nodes, and datacenter hosting companies. When you visit this page, we look up your IP and check multiple data points: whether the IP belongs to a known VPN or proxy service, whether it's registered to a datacenter or hosting provider (rather than a residential ISP), and whether it has flags indicating proxy or VPN usage.
This detection method is not 100% foolproof — some premium VPN services use residential IP addresses that don't appear in proxy databases, and some legitimate business connections may be incorrectly flagged because they route through datacenter infrastructure. However, for most common VPN and proxy services, detection is highly reliable.
Why Check If Your VPN Is Working?
If you're using a VPN to protect your privacy, you want to confirm it's actually working. VPN leaks can expose your real IP address through DNS leaks, WebRTC leaks, or VPN disconnections. By checking your IP with our tool, you can verify that websites see your VPN's IP address rather than your real one. This is especially important on public Wi-Fi networks where you need VPN protection the most.
Who Uses VPN Detection?
Streaming services use VPN detection to enforce geographic content licensing. Banks and financial services flag VPN connections as potential fraud indicators. E-commerce sites detect proxies to prevent fraud and enforce regional pricing. Security teams verify that employees are connecting through approved VPN gateways. Network administrators check whether traffic is being tunneled through unauthorized channels.
Privacy, Accuracy & Security
Privacy: We only see your public IP for this check and do not store it for tracking. Accuracy: Detection uses known VPN/proxy/datacenter databases; some residential-style VPNs may not be flagged. Security: All requests use HTTPS. For full IP details (location, ISP, ASN), use our IP address lookup or What is my IP. For domain or network checks, try DNS lookup, ping test, traceroute, or our port checker.
Frequently Asked Questions About VPN Detection
How can I tell if my VPN is working?
Visit this page with your VPN connected. If the tool detects a VPN/proxy, your VPN is successfully masking your real IP. You should also see a different IP address than your normal one, and the location should match your VPN server's location.
Why does this tool say I'm using a VPN when I'm not?
Some ISPs use carrier-grade NAT or route traffic through shared infrastructure that looks like datacenter hosting. Business internet connections may also be flagged because they use static IPs in IP ranges that overlap with hosting providers.
Can websites detect all VPNs?
No. While most commercial VPN services can be detected because their IP ranges are known, some premium VPNs use residential IP addresses that are very difficult to distinguish from normal home connections. Detection technology is constantly evolving, as are VPN evasion techniques.
What is a VPN leak?
A VPN leak occurs when your real IP address is exposed despite being connected to a VPN. This can happen through DNS leaks (your DNS queries go to your real ISP), WebRTC leaks (browser feature that can reveal your real IP), or IPv6 leaks (your VPN only tunnels IPv4 traffic).
Is this VPN check free?
Yes, our VPN detection tool is completely free. No signup, no API key, and no limits on usage.
