DNS Leak Test
Full privacy scan: IP address, DNS servers, WebRTC leaks, and VPN/Tor detection.
🧠 What Is a DNS Leak?
Every time you open a website, your device asks a DNS server for directions. If you're not using a privacy-friendly setup, these requests are visible to your ISP. This test checks your IP address, which DNS servers handle your queries, and whether WebRTC is exposing your real IP behind a VPN.

Frequently Asked Questions
What is a DNS leak?
A DNS leak occurs when your DNS queries are sent outside your VPN tunnel, exposing your browsing activity to your ISP. This can happen even when your VPN is active.
How do I fix a DNS leak?
To fix a DNS leak, use a VPN with built-in DNS leak protection, configure your OS to use your VPN's DNS servers, or switch to a privacy-focused DNS provider like Mullvad or Cloudflare.
What is a WebRTC leak?
A WebRTC leak happens when your browser exposes your real IP address through the WebRTC protocol, bypassing VPN protection. This test detects any such exposure.
