Not very interesting at all. It looks perfectly fine for a static IP
address on a /24 network.

Nope, not at all. That combination will work just fine, though the
network statement is misleading and unnecessary.

Best would be to omit it altogether. Modern Linux doesn't need it and as
far as I know just ignores it. I can't actually remember ever using it.

Sarcasm doesn't help anyone, and this error has already been pointed out
and (hopefully) fixed.

The broadcast address can usually be left out altogether. Linux will
work it out for you. In this particular case, if it were to be kept, it
should be 192.168.144.255.
