Common Questions
What is a DNS leak?
A DNS leak occurs when your DNS queries are sent outside your VPN tunnel — typically to your ISP's DNS servers. This reveals which websites you visit to your ISP, even though your traffic appears encrypted. Use the DNS Leak Test to check if your VPN is leaking.
What is a WebRTC leak?
WebRTC is a browser technology for real-time communication (video calls, voice chat). It can expose your real IP address even when you're connected to a VPN, because it bypasses the VPN tunnel. The WebRTC Leak Test shows whether your browser is affected.
What does "What Is My IP" tell me?
The What Is My IP tool shows your public IP address — the address visible to websites and servers you connect to. It also shows your ISP, approximate location, timezone, and ASN. If you're using a VPN, you should see the VPN server's IP, not your real IP.
How do I test if my VPN is working?
Use three tools together: (1) What Is My IP — confirm the IP matches your VPN server, not your home IP. (2) DNS Leak Test — verify DNS queries go through the VPN. (3) WebRTC Leak Test — ensure your real IP isn't exposed through the browser. All three passing means your VPN is working correctly.
What is browser fingerprinting?
Browser fingerprinting is a tracking technique that identifies you based on your browser's unique combination of settings — screen resolution, fonts, timezone, WebGL renderer, and other attributes. Unlike cookies, fingerprints cannot be deleted. The Browser Fingerprint Test shows you exactly what data advertisers can collect.
What is a port and how do I check if one is open?
A port is a numbered endpoint on a network device. Open ports accept incoming connections; closed or filtered ports reject them. Use the Port Checker to test whether a specific TCP port is open on any server or IP address — useful for verifying server configurations and firewall rules.

What To Do If You Find a Leak
If any of our privacy tests reveal a leak, here is the recommended action plan.
DNS Leak Detected
- Switch VPN protocol (try WireGuard)
- Enable VPN kill switch
- Configure VPN DNS override in settings
- Disable system DNS-over-HTTPS while VPN is active
WebRTC Leak Detected
- Install uBlock Origin (blocks WebRTC leaks)
- Disable WebRTC in browser flags
- Use a VPN with WebRTC leak protection
- Switch to Firefox (better WebRTC control)
Real IP Still Visible
- Disconnect and reconnect your VPN
- Choose a server closer to your location
- Try a different VPN protocol
- Contact your VPN provider support
