   The IPv4 and IPv6 addresses, Netmask, MAC address, Gateway, and DNS settings are displayed on the screen above the interface selection dialog.

3. For example, select IPv4 Address and press Enter.

   The on-screen dialog displays the current IP address.

4. Navigate into the dialog and change the IP address to 0.0.0.0, then press Enter.
