Manage exposure of local IP addressess by WebRTC
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 80, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge 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. Example value: https://www.contoso.com *contoso.com*
Registry

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
