Understanding WebRTC Leaks
WebRTC leaks can expose your real IP address even when you're using a VPN, compromising your privacy and anonymity. WebRTC is designed to facilitate real-time communication, but this functionality can inadvertently reveal network information that you might want to keep private.
What is WebRTC?
WebRTC (Web Real-Time Communication) is a browser feature that enables direct peer-to-peer communication between browsers for video calls, audio chat, and file sharing - without requiring plugins. To establish these connections, WebRTC uses STUN servers to discover your public IP address and port information. This is how apps like Google Meet, Zoom, and Discord work directly in your browser. Note: Even when using a VPN, WebRTC can sometimes reveal your original IP address. This is known as a WebRTC leak.
How to prevent WebRTC leaks
Browser Extensions: Most privacy-focused browsers offer extensions that block WebRTC requests. Popular options include "WebRTC Leak Shield" or "uBlock Origin" with WebRTC blocking enabled. Browser Settings: Firefox: Enter about:config in the address bar, search for media.peerconnection.enabled and set it to false. Chrome: WebRTC cannot be fully disabled via settings, but extensions can help. Brave: Built-in WebRTC leak protection - should work automatically. VPN Settings: Some VPN apps include "WebRTC leak protection" - check your VPN provider's settings.
What is a DNS leak?
DNS (Domain Name System) translates website names into IP addresses. When you visit a website, your browser asks a DNS server to resolve the domain name. When using a VPN, ideally all your DNS requests should go through the VPN's encrypted tunnel. A DNS leak occurs when these requests escape the VPN tunnel and are visible to your ISP or other parties. How to check: Your detected DNS servers should ideally be different from your ISP's default servers. If they match your ISP, your browsing activity could be logged.
How to prevent DNS leaks
Use a reputable VPN: Quality VPN providers route all DNS requests through their own encrypted servers. Most paid VPNs include this by default. Manual DNS configuration: You can change your DNS servers to privacy-focused alternatives: Cloudflare: 1.1.1.1 and 1.0.0.1, Google: 8.8.8.8 and 8.8.4.4, Quad9: 9.9.9.9 (also blocks malicious domains). VPN + DNS-over-HTTPS: Enable DNS-over-HTTPS in your browser for additional privacy.
Do you log or store my IP address?
No. This tool is 100% ad-free with no tracking, no logging, and no signup required. Your IP address and network information are never sent to our servers, stored, or logged in any way. How it works: The tool makes API calls directly from your browser to third-party IP lookup services. We don't intercept, store, or log any of this data. Your privacy is completely protected.
Why is this WebRTC Leak Test completely free?
Our main business at EWU IT Solutions relies on enterprise client services, not ad revenue. Since this WebRTC test executes entirely within your browser environment without requiring heavy server processing, hosting costs are practically zero. We offer it for free to help the community stay secure.
Are you tracking my real IP address if it leaks during the test?
No. The phrase "If you aren't paying for the product, you are the product" does not apply here. Any IP addresses discovered during this WebRTC scan stay strictly on your device. We do not use tracking cookies or analytics to monitor your test results.
