Ipcalc-tools talks......

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.
