subnet mask of the adapter is 255.255.255.0 and the gateway address is set to
0.0.0.0. The adapter does not have a host name assigned, or use any Domain

If you set the switches to an invalid number (such as 000, or a value greater than

settings. This is useful in situations where you want to reuse a module that has an
unknown configuration.
