Parallels Desktop provides a closed network that is accessible only to macOS and Windows. macOS is connected to this network via the Parallels Host-Only Networking adapter automatically created on your Mac during the Parallels Desktop installation. The addresses for Windows are provided by the Parallels DHCP server.
To configure Windows to use Host-Only Networking:
Do one of the following:
Click the Parallels Desktop icon in the menu bar and choose Configure.
If the Parallels Desktop menu bar is visible at the top of the screen, choose Actions > Configure.
Click Hardware and then click Network.
In the Network pane, make sure that the Host-Only option is selected.
For information about troubleshooting networking problems, refer to the Parallels knowledge base available on the Parallels website.
