Question 1

What is a WebRTC leak?

Accepted Answer

WebRTC (Web Real-Time Communication) is used for video calls and peer-to-peer connections. Browsers can expose your local (private) IP address through WebRTC even when using a VPN. Websites can then link your real network to your VPN session.

Question 2

Which browsers leak WebRTC?

Accepted Answer

Chrome, Firefox, Edge, and Opera can expose local IPs via WebRTC. Safari has stricter controls. Use browser extensions to disable WebRTC or block it in settings when privacy matters.

Question 3

How do I fix WebRTC leaks?

Accepted Answer

Install a WebRTC-blocking extension (e.g. uBlock Origin with WebRTC block, or dedicated WebRTC Leak Prevent). Or use a browser that blocks it. KloxVPN apps use a VPN tunnel—your traffic is encrypted, but WebRTC in the browser can still leak your local IP to websites.

Question 4

Does a VPN protect against WebRTC leaks?

Accepted Answer

A VPN encrypts your traffic and hides your public IP. But WebRTC runs in the browser and can reveal your local network IP (e.g. 192.168.x.x) to JavaScript. The VPN cannot block this—you must disable WebRTC in the browser or use a privacy-focused browser.
