Information
This setting lets you decide whether an employee's LocalHost IP address shows while making phone calls using the WebRTC protocol.
The recommended state for this setting is: Enabled.
Rationale:
WebRTC is a Real-Time Communications open source project supported by all major browsers. Allowing a system's local IP address to be shared may be considered a privacy concern.
Impact:
The employee's LocalHost IP address will be hidden while making phone calls using WebRTC.
Solution
To establish the recommended configuration via GP, set the following UI path to Enabled:
Computer Configuration\Policies\Administrative Templates\Windows Components\Microsoft Edge\Prevent using Localhost IP address for WebRTC
Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MicrosoftEdge.admx/adml that is included with the Microsoft Windows 10 Release 1511 Administrative Templates (or newer).
Note #2: In the Microsoft Windows 10 Release 1511 Administrative Templates, this setting was named Don't allow WebRTC to share the LocalHost IP address, but it was renamed starting with the Windows 10 Release 1607 & Server 2016 Administrative Templates.
Default Value:
Disabled. (An employee's LocalHost IP address will be shown while making phone calls using WebRTC.)
