Controls which IP addresses and network interfaces WebRTC can use when establishing connections for specific URL patterns. How It Works: Accepts a list of URL patterns, each paired with a handling type. WebRTC evaluates patterns sequentially; the first match determines the handling type. If no match is found, WebRTC defaults to the WebRtcLocalhostIpHandling WebRtcLocalhostIpHandling. policy. This policy applies only to origins—URL path components are ignored. Wildcards (*) are supported in URL patterns. Supported Handling Values: default – Uses all available network interfaces. default_public_and_private_interfaces – WebRTC uses all public and private interfaces. default_public_interface_only – WebRTC uses only public interfaces. disable_non_proxied_udp – WebRTC uses UDP SOCKS proxying or falls back to TCP proxying. More Information: Valid input patterns: https://go.microsoft.com/fwlink/?linkid=2095322 Handling types: https://tools.ietf.org/html/rfc8828.html#section-5.2 Example value: [ { "url": "https://www.example.com", "handling": "default_public_and_private_interfaces" }, { "url": "https://[*.]example.edu", "handling": "default_public_interface_only" }, { "url": "*", "handling": "disable_non_proxied_udp" } ]

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.
