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?

/bin/ipcalc - part of the "initscripts" package.

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.

I'm pretty sure this is the one that I was using before.

Thanks loads for the help.

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.

No, it indeed does not. My brain skipped over the part of
your original post that specified you wanting to do
ranges. I blame all the food consumed today

Also available in the epel repo if you want it in rpm
format.
