In this window, you can make the necessary changes to the settings of the Parallels DHCP servers for IPv4 and IPv6. These servers, enabled by default, automatically assign IP addresses to the virtual machines operating in the host-only networking mode. To disable any of these servers, clear the corresponding option.
To restore the default settings, click Restore Defaults.
