URLs for which local IPs are exposed in WebRTC ICE candidates

Computer and userIntune-readyWebRtcLocalIpsAllowedUrls

Supported on Microsoft Windows 7 or later

1.93.137

What it does

Patterns in this list will be matched against the security origin of the requesting URL. If a match is found or chrome://flags/#enable-webrtc-hide-local-ips-with-mdns is Disabled, the local IP addresses are shown in WebRTC ICE candidates. Otherwise, local IP addresses are concealed with mDNS hostnames. Please note that this policy weakens the protection of local IPs if needed by administrators. Example value: https://www.example.com *example.com*

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: WebRtcLocalIpsAllowedUrlsDesc
