Manage exposure of local IP addressess by WebRTC

Supported versions

  • On Windows and macOS since 80 or later

Description

Specifies a list of origins (URLs) or hostname patterns (like "contoso.com") for which local IP address should be exposed by WebRTC.

If you enable this policy and set a list of origins (URLs) or hostname patterns, when edge://flags/#enable-webrtc-hide-local-ips-with-mdns is Enabled, WebRTC will expose the local IP address for cases that match patterns in the list.

If you disable or don't configure this policy, and edge://flags/#enable-webrtc-hide-local-ips-with-mdns is Enabled, WebRTC will not expose local IP addresses. The local IP address is concealed with an mDNS hostname.

If you enable, disable, or don't configure this policy, and edge://flags/#enable-webrtc-hide-local-ips-with-mdns is Disabled, WebRTC will expose local IP addresses.

Please note that this policy weakens the protection of local IP addresses that might be needed by administrators.
