WOW. I can't believe that ifconfig really needs that info. I couldn't work
out the math for you in writing, but after a year and a half, I can
convert CIDR notation to IP/Netmask and give you a network and broadcast
address in my head in under 5 seconds. The math should be disgustingly
simple to implement, and I'm surprised that it doesn't do it.
I think I need to sit and think about this one. It really threw me for a
loop.
