The Set-IpamConfiguration is the command that can be used to modify the configuration for the system running IPAM (IP Address Management) server.
The -GpoPrefix<String> parameter mentions the unique GPO prefix name that is used by IPAM for creating the group policy objects. This parameter is used only when the ProvisioningMethod parameter is assigned the value as Automatic.
