This setting does not apply to desktop apps. A comma-separated list of IP address ranges that are in your corporate network. If you enable this policy setting, it ensures that apps with the Home/Work Networking capability have appropriate access to your corporate network. These addresses are only accessible to apps if and only if the app has declared the Home/Work Networking capability. Windows Network Isolation attempts to automatically discover private network hosts. By default, the addresses configured with this policy setting are merged with the hosts that are declared as private through automatic discovery. To ensure that these addresses are the only addresses ever classified as private, enable the "Subnet definitions are authoritative" policy setting. If you disable or do not configure this policy setting, Windows Network Isolation attempts to automatically discover your private network hosts.
