Where did the wizard obtain the ip address that appears in the preferred dns server ipv4 address text box by default?

The wizard typically obtains the default IP address for the preferred DNS server from the system's network configuration settings or from a preset configuration defined by the operating system or network settings. This default address is often set to a commonly used public DNS server, such as those provided by google (8.8.8.8) or the internet Service Provider (ISP). In some cases, it could also be derived from DHCP settings if the network is configured to assign DNS servers automatically.
