A DNS or WebRTC leak happens when your main traffic routes through a proxy, but domain requests or P2P connections bypass it. This reveals your real IP address or local ISP. Such leaks ruin your anonymity and lead to immediate account bans.
Fixing these leaks requires adjusting your browser or anti-detect software settings to force all requests through the proxy tunnel. Below, we explain how to identify these vulnerabilities in five minutes and configure your system to prevent them.
How Leaks Expose Your Setup
Browsers use the Domain Name System to translate website names into numerical IP addresses. If your system ignores proxy settings for this step, the target website easily detects your real internet provider and original region.
WebRTC establishes direct peer-to-peer connections for audio and video streaming within the browser. It bypasses standard routing entirely, exposing your actual local network details and public IP address to the visited page.
- DNS leaks expose your real physical location and local home ISP.
- WebRTC vulnerabilities reveal your true public IP address.
- Anti-fraud systems flag these critical mismatches immediately.
Checking Your Connection
You can verify your current proxy setup using specialized online checking tools. Open a new browser tab and visit trusted testing services like BrowserLeaks or Whoer to thoroughly analyze your visible digital footprint before starting any real work.
Look specifically at the DNS and WebRTC sections in the generated report. If the displayed IP addresses belong to your home provider instead of your proxy, you have an active leak that requires immediate attention.
Keep in mind that a mismatch between proxy IP and DNS IP is normal if both belong to the same mobile carrier. Learn more in our guide on how to choose a mobile proxy provider.
Securing WebRTC Connections
Regular browsers require third-party extensions to manage WebRTC connections, but modern anti-detect browsers offer built-in controls. You should never disable WebRTC entirely, as security systems will detect this as a suspicious anomaly.
Instead, configure your anti-detect browser to spoof the WebRTC IP, carefully matching it to your active proxy address. This smart approach keeps your digital profile looking natural and trustworthy to complex anti-fraud algorithms.
- Open your specific profile settings within the anti-detect browser.
- Locate the WebRTC section and select the Alter or Spoof option.
- Ensure the assigned IP address matches your external proxy address.
Routing DNS Through Proxies
To stop DNS leaks, force the browser engine to resolve all domain names directly through the proxy server. In standard Firefox, this is achieved by enabling the Proxy DNS when using SOCKS v5 option in the network settings.
Anti-detect browsers usually handle this routing automatically when you create a new working profile. However, you should always verify that custom DNS settings are disabled so the mobile proxy provider’s native DNS takes absolute priority.
Using the mobile carrier’s native DNS looks much more authentic than forcing public resolvers like Google. This detail drastically reduces the chance of triggering automated security alerts on target platforms.
Gateway-Level Protection
Beyond simple browser settings, the underlying proxy infrastructure itself plays a crucial role in preventing detection. Standard server proxies often leak sensitive data through their basic TCP stack behavior, revealing their true datacenter origins.
We use passive OS fingerprinting spoofing natively at the gateway level. Your connection appears exactly like a regular mobile device, completely hiding the server infrastructure without relying on client-side software modifications.
Understanding these technical nuances helps when comparing mobile proxy market prices and evaluating features. Proper spoofing ensures maximum account survival rates.
