broadcast

I'm new to advanced network administration and I would like to do some testing with UDP broadcasting, so I need a broadcast address on my loopback interface. The machine is offline, in other words, there is no network.

How can I accomplish that through ifconfig without having to buy a switch as one user in the comments suggested. In Linux all i have to do is use 127.255.255.255 and broadcasts work fine without any network or any switch. If I have a network i can just use 255.255.255.255, obviously.
