FAQ

What does this tool check?

It checks 5 things: your public IP address (and whether it belongs to a VPN), WebRTC leaks (browser API that can bypass VPN), DNS leaks (whether DNS requests go through your ISP), IPv6 leaks, and basic browser information.

What is a WebRTC leak?

WebRTC is a browser technology for real-time communication. It can reveal your real IP address even when you're connected to a VPN. This test checks if your browser exposes local or public IPs through WebRTC.

What is a DNS leak?

When you visit a website, your browser sends a DNS request to translate the domain name to an IP address. If this request goes to your ISP's DNS server instead of your VPN's, your ISP can see which sites you visit.

How is the anonymity score calculated?

The score is based on 5 tests: IP detection (+30), no DNS leak (+25), no WebRTC leak (+20), no IPv6 leak (+15), and VPN/proxy detected (+10). Maximum score is 100.

How are the tests performed?

IP detection uses a one-time server request. WebRTC, DNS, and browser fingerprint tests run in your browser via JavaScript APIs.

Why does it show my real IP even with VPN on?

This usually means WebRTC is leaking your IP. Disable WebRTC in your browser settings or use a browser extension. Some VPN apps have a "WebRTC protection" option.

Does this work on mobile?

Yes. All tests work on mobile browsers. WebRTC leak test may behave differently on iOS Safari due to Apple's privacy restrictions.
