Check if your browser is leaking your real IP address through WebRTC
What is WebRTC?
WebRTC stands for Web Real-Time Communication. As the name suggests, this technology allows for real-time communication between browsers without requiring an intermediate server (after the connection has been already established). The benefits of WebRTC include:
- •It reduces the lag time for video chat, audio chat, live streaming, and even large file sharing
- •It's free for both personal and commercial use
- •It utilizes technology that is constantly improving
- •It's open-source software, as opposed to an extension or plugin
- •It's available for mobile applications
- •It offers better sound quality as opposed to Flash with adjustable built-in microphone settings
Although WebRTC was originally developed by Google, many browsers support this technology, including Microsoft Edge, Mozilla Firefox, Opera, Google Chrome, and Safari.
WebRTC is most notably recognized for its ability to enhance video and audio chats, but it is also a useful tool for other applications, such as the transfer of data.
What does WebRTC local IP exposure mean?
WebRTC can expose your local IP address (such as 192.168.x.x or 10.x.x.x) when establishing video or audio communication. However, it's important to understand that local IP addresses are private network addresses and cannot identify you or reveal your real location. Your public IP address, which is what actually matters for privacy, remains fully protected by LockNet VPN.
Is local IP exposure a problem?
No. Local IP exposure through WebRTC is normal browser behavior and does not compromise your privacy. Local IPs (192.168.x.x, 10.x.x.x, 172.16.x.x) are private network addresses that cannot be used to identify you or your location. LockNet VPN protects your real public IP address, which is what actually matters for privacy and security.
Is local IP exposure a threat?
Local IP exposure through WebRTC is a normal browser behavior and does not pose a threat to your privacy. LockNet VPN fully protects your real public IP address, which is what actually matters. The local IP addresses that WebRTC may expose (like 192.168.x.x) are private network addresses that cannot identify you or reveal your location. This is why major VPN providers don't consider local IP exposure to be a leak.
How to protect yourself from WebRTC leaks?
You can disable some of the functionality of WebRTC in your browser's settings. Here's how to do it on different browsers:
How to disable WebRTC on Google Chrome?
It's best to use an extension to disable WebRTC on Chrome because doing it manually can cause damage to the functionality of your browser. Here are a couple of extensions you could use:
- •WebRTC Network Limiter is an official Google extension that tinkers with WebRTC settings to stop any IP leaks without completely blocking it. Since WebRTC Network Limiter doesn't completely block WebRTC, the services that use WebRTC will still work on your browser.
- •uBlock Origin isn't dedicated to WebRTC alone, but it has a feature to disable it on your browser.
How to disable WebRTC on Safari?
Safari takes care of WebRTC leaks better than other browsers by blocking websites from accessing your camera and microphone by default. However, you can still disable it from the browser to be extra careful.
Note: Websites that use WebRTC for their services will not work!
- 1.Go to Safari > Preferences. Check "Show Develop menu in menu bar".
How to disable WebRTC on Firefox?
You can disable WebRTC in the browser settings by following these steps:
Note: Websites that use WebRTC for their services will not work!
- 1.Type this in the URL bar and click Enter:
about:config - 2.Search for
media.peerconnection.enabled - 3.Set it to
false
