What Is WebRTC?

WebRTC lets browsers set up real-time peer-to-peer audio, video and data connections without a plugin — using signaling and ICE candidate gathering rather than routing every call through one central server.

WebRTC Leaks Explained

WebRTC lets your browser learn its own public IP address for real-time features like video calls — and under the wrong conditions, a page can read that address even through a VPN.

How WebRTC Can Reveal IP Addresses

WebRTC's ICE candidate-gathering process learns your public address by design — modern browser protections limit what a page can extract from that process, but don't eliminate the underlying exposure entirely.

How to Run a WebRTC Leak Test

A WebRTC leak test compares every address your browser's real-time connection feature reveals against your actual HTTP exit IPs — here's how to run one and read the result.

VPN WebRTC Leaks: Diagnosis Before Disabling Features

Before disabling WebRTC entirely over leak concerns, check specifically whether the exposed address actually bypasses your VPN tunnel — many results that look alarming turn out to be expected or easily fixed with a narrower change.

Browser WebRTC Privacy Has Changed

WebRTC privacy behavior has changed meaningfully across browser versions — mDNS masking, tightened permission models, and evolving relay policies mean older assumptions about WebRTC exposure may no longer apply.

WebRTC STUN Explained

STUN servers let a browser learn its own public-facing address for connection setup — a narrow, specific job that doesn't relay the actual call media itself.

Public IP Exposure Through WebRTC

Distinguishing an expected VPN exit candidate from an unexpected ISP-assigned one is the key skill for reading a WebRTC leak test result correctly.

Chrome WebRTC Leak Checks

Testing directly, rather than relying on outdated flag-based instructions, is the reliable way to check Chrome's current WebRTC leak behavior — which is shaped by extensions, enterprise policy, and VPN interaction, not a fixed setting.

Firefox WebRTC Leak Checks

Firefox offers more direct, built-in privacy controls over WebRTC than some other browsers — testing first clarifies whether you actually need to use them.

Microsoft Edge and WebRTC Privacy

Edge is Chromium-based and shares much of Chrome's WebRTC behavior, but enterprise policies, extensions and OS-level network paths specific to Edge deployments can still produce different results.

Safari WebRTC Privacy on macOS and iPhone

Safari's WebRTC privacy story includes a distinctive piece — iCloud Private Relay — with its own boundaries and interaction with VPN routing worth understanding separately from other browsers.
