I'm looking to convert an IP string (ranges, subnet masks or wild-carded 
IP's) in to an array of IP strings:

eg. "192.168.1.1 - 192.168.1.5" => ["192.168.1.1", "192.168.1.2", 
"192.168.1.3", "192.168.1.4", "192.168.1.5"]

Before I embark on this, is there already a ruby class that does it or 
some of this?

I've checked out the NET classes already.

Many thanks, K.
