WebRTC Leak Test FAQs
What is a WebRTC IP Leak?
WebRTC (Web Real-Time Communication) is a browser technology for audio/video streaming. However, its STUN protocol can bypass proxy servers and VPN tunnels to reveal your true local network IP address (e.g. 192.168.1.5) and ISP public IP address to website scripts.
Why are WebRTC IP leaks dangerous for multi-profile managers?
If you manage multiple profiles using proxies, a single WebRTC leak exposes your real home/office IP across all profiles. Platforms like Facebook Ads, Google Ads, and eBay use WebRTC candidate matching to detect and flag linked accounts.
How does BeastBrowser prevent WebRTC IP leaks?
BeastBrowser provides built-in WebRTC management options: Disable WebRTC completely, Replace WebRTC candidates with your proxy IP address, or restrict candidate gathering to public proxy interfaces only.
