Frequently asked questions
Everything you need to know about the VPN & Proxy Checker.
Back to the toolHow do websites detect VPNs?
Mostly by checking whether your IP belongs to a data center or VPN company, and by comparing signals like timezone and WebRTC with your IP location.
What is a WebRTC leak?
WebRTC (used for video calls) can reveal your real IP address to websites even when a VPN is on. Many VPN apps and browser extensions can block it.
My VPN is on but the checker says “no VPN” — is that bad?
Not necessarily. Residential and good VPN servers are harder to detect. What matters is that your real IP and location do not leak.
Is this 100% accurate?
No detection is perfect. The tool shows the signals websites commonly use so you can understand how your connection appears.
How do I fix a timezone leak?
Set your device timezone to match the VPN server location, or use a VPN with location spoofing features.
