CentOS - Dec 2009 - ip range cidr calculator

I found a command-line program that did this once before, used it for a
while and then forgot about it until right now and I'll be damned if I
can find it again.

A command line IP calculator that takes an address range and give it
back in cidr format.

I found an online one that does this here:

http://www.ipaddresslocation.org/subnet-mask-calculator.php

But I would prefer to have the commandline one back again.

Does anyone know what it's called and where it can be found?

I like the one at <http://jodies.de/ipcalc-archive/ipcalc-0.41/ipcalc> 
which also gives Cisco wildcard masks as well as all the other useful 
things.

As far as I can tell, that one doesn't do ranges (from a.b.c.0 to
a.b.e.255 stuff).  At least, if it does I haven't figured out the magic
incantation to get it to do that.

The one that Barry posted here does ranges.  I'm pretty sure it's the
same one that I was using before.

This time I have put it into a directory that I'm not likely to lose.

Thanks for the help.
