I know I'm late, but did you try the dread "ipcalc" program that comes
with Linux?.  E.g.

	[root at prophead root]# ipcalc -n 192.168.0.71/26
	NETWORK=192.168.0.64

That's your first address (the network)

	[root at prophead root]# ipcalc -b 192.168.0.71/26
	BROADCAST=192.168.0.127

And that's the last address (the broadcast).  So, 192.168.0.71/26
covers 192.168.0.64 through 192.168.0.127, inclusive.  Not too hard, eh?
"man ipcalc" for more details.
