Frequently Asked Questions
How does VPN detection work?
VPN detection analyzes multiple factors including the IP's ASN (Autonomous System Number), ISP information, hosting provider data, geographic consistency, and known VPN server databases. We check if the IP belongs to known VPN providers or datacenter networks commonly used for VPN services.
How accurate is VPN detection?
VPN detection accuracy varies but is generally 80-95% for commercial VPN services. Detection is easier for well-known VPN providers but may miss private VPN servers or new providers. Some legitimate services may be flagged if they use hosting providers commonly associated with VPNs.
What's the difference between VPN, proxy, and Tor?
A VPN encrypts all your traffic and routes it through a secure server. A proxy only routes specific traffic (like web browsing) without encryption. Tor routes traffic through multiple encrypted layers for maximum anonymity. All three can hide your real IP address.
Why would someone want to detect VPNs?
VPN detection is used for fraud prevention, content licensing compliance, security monitoring, and enforcing geographic restrictions. Some services block VPNs to prevent abuse or comply with regional licensing agreements.
Can this tool detect all VPNs?
No detection method is 100% foolproof. This tool can identify most commercial VPN services and many proxy services, but sophisticated or private VPN setups may not be detected. The confidence score indicates how certain we are about the detection.
