WebRTC pode vazar seus IPs reais local e publico para sites mesmo usando VPN. Clique Iniciar para detectar o que seu navegador expoe.

IP publico -

The IP address websites see. With a VPN on this should match your VPN server, not your ISP.

IPs locais -

Your private network address (192.168.x, 10.x). Modern Chrome hides this behind an mDNS hash ending in .local.

IPv6 -

Your IPv6 address. If your VPN does not tunnel IPv6, this leaks even when IPv4 is protected.

How to fix a WebRTC leak

If your real public IP appeared above while you had a VPN active, your VPN is leaking. Pick the section for your browser and follow the steps.

Chrome and Edge

Chrome has no built-in WebRTC toggle. Install the official "WebRTC Network Limiter" extension from the Chrome Web Store (made by Google) and set it to "Use default public and private interfaces." Or switch to a VPN with built-in WebRTC leak blocking (Mullvad, ProtonVPN, NordVPN, ExpressVPN all advertise it).

Firefox

Type about:config in the address bar and accept the warning. Search for media.peerconnection.enabled and double-click to set it to false. This disables WebRTC entirely - video calls in Google Meet, WhatsApp Web, and Discord browser will stop working until you turn it back on.

Brave

Paste brave://settings/privacy into the address bar, scroll to "WebRTC IP handling policy," and change it to "Disable Non-Proxied UDP." Brave is the only major browser with this option in the UI, no extension required.

Safari (macOS / iOS)

On macOS: Safari > Settings > Advanced > Show features for web developers > Feature Flags > disable WebRTC Platform UDP Sockets. On iOS: Settings > Safari > Advanced > Experimental Features > toggle WebRTC mDNS ICE candidates on.

Best long-term fix: a VPN that blocks WebRTC at the app level

If you need video calls to keep working, do not disable WebRTC - switch to a VPN that routes WebRTC traffic through the tunnel or blocks it at the OS level. Mullvad, ProtonVPN, NordVPN, and ExpressVPN all do this correctly. Many cheap and free VPNs do not.

Seeing a .local address? That is not a leak

Chrome replaces your real local IP with a hashed mDNS string like a1b2c3d4.local. This is a privacy feature added in Chrome 76 (2019) - the hash cannot be tracked back to your real network and does not help fingerprinting.
