[lug] Calculating network addresses

[Brian Jarrett]

Ian,

The easiest _algorithm_ is to AND the IP address and Subnet Mask.  This is
how networking devices work.  Not sure of how to do it in BASH, but any
programming language would handle it for sure.

Does anyone hava  quick and dirty alogorithm for extrapolating a network

in bash?
