ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design sub- and supernetworks. It is also intended to be a teaching tool and presents the results as easy-to-understand binary values.

nice stuff
This stuff is very nice. I have a problem with the colours,
I don't like'em but since is Perl code you can modify it, right? :)
To compile ipsc (freshmeat.net/projects..., a similar project, you need some
darn lib. For this you just need Perl. Oh well, it's not
that advanced but who cares, it's good for the most stuff I do. And it also
shows me the IPs in binary format so it gets me thinking :) good
learning tool too.
