Set IP address for Zoom Mesh local detection (Recommendation Setting)
Zoom 5.17.5
Supported on: Microsoft Windows XP SP2 or later
Description
Default policy is empty. If this policy is a valid IP address, this policy will allow admins to specify a valid IP address to be a UDP multicast IP for Zoom apps to declare themselves and detect each other in their local sub-network (255.255.255.0). Admins can choose other IP addresses within the range of [224.0.0.1, 239.255.255.255]. If this policy is empty or invalid, this policy will set as 224.0.0.1 by default. If this policy is not set, client will use the default setting.
Registry
HKLM
Software\Policies\Zoom\Zoom Meetings\Recommended\Meetings REG Builder
BETAConfigure the state and elements to generate .reg, PowerShell, Intune, and SCCM outputs.
These exports replicate the policy's registry effect. Editing the registry directly is not the same as applying the GPO through the management console (no gpupdate, no central reporting). Test before production; HKLM changes require administrator rights.
