.SH NAME
ipcalc - An IPv4 Netmask/broadcast/etc calculator
.SH SYNOPSIS
\fB ipcalc \fR [options] \fIADDRESS\fR[[/]\fINETMASK\fR] [\fINETMASK\fR]
.SH DESCRIPTION
\fBipcalc\fR takes an IPv4 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.
