Comprehensive testing for IP, DNS, WebRTC, and torrent leaks to ensure your VPN is protecting your privacy
One-Click DNS, IP, WebRTC & Torrent Check.
This test will check your connection twice: first without VPN, then with VPN connected.
A VPN leak happens when your device accidentally exposes your real IP address, physical location, or even your internet traffic outside of the encrypted VPN tunnel. This completely defeats the purpose of using a VPN, which is to protect your online identity and privacy.
Even with a VPN active, various types of leaks can reveal your true identity, location, and browse habits to third parties like your Internet Service Provider (ISP), government agencies, or malicious attackers. Your privacy depends on your VPN being leak-proof.
What is it? IPv6 leaks are very common. Many VPNs handle IPv4 traffic well, but don't properly manage IPv6 connections, allowing them to bypass the VPN entirely.
How does it happen? Your device might be set up to use IPv6, but your VPN only routes IPv4 traffic. This creates a "leak" where IPv6 requests go straight to your ISP.
The danger: Websites can detect your real IPv6 address, revealing your actual location, ISP, and potentially even your personal identity.
What is it? Web Real-Time Communication (WebRTC) allows direct communication within your web browser. Unfortunately, it can also be exploited to expose your real IP address.
How does it work? WebRTC uses STUN servers to find your local and public IP addresses for direct connections. Malicious websites can access this information using simple JavaScript.
The danger: Your real IP can be exposed even with a VPN running, completely bypassing its protection. This is especially risky because it often happens silently in the background.
Good to know: WebRTC leaks affect all major browsers, including Chrome, Firefox, Safari, and Edge. The leak occurs at the browser level, not the network level.
What is it? A Domain Name System (DNS) leak occurs when your device sends DNS queries outside the VPN tunnel-typically to your ISP's DNS servers instead of your VPN provider's.
What does it reveal? Your ISP can see and log every website you visit, your browse patterns, and potentially your location.
Common causes:
What is it? If different online services report varying IP addresses when you're connected to your VPN, it suggests your VPN isn't routing all traffic correctly, or there are multiple paths your data is taking.
What to look for: When connected to a VPN, all legitimate IP checking services should report the same IP address. Inconsistencies might mean a leak or connection issues.
What is it? Older browser plugins like Java and Flash have known security flaws that can be exploited to reveal your true IP address and bypass VPN protection.
Why are they dangerous? These plugins can make direct network connections outside of your browser's normal security sandbox, potentially bypassing your VPN. It's generally safest to remove or disable them.
