.SH DESCRIPTION
|
||
|
|
\fBipcalc\fR provides a simple way to calculate IP information for a host.
|
||
|
|
The various options specify what information \fBipcalc\fR should display
|
||
|
|
on standard out. Multiple options may be specified. An IP address to
|
||
|
|
operate on must always be specified. Most operations also require a
|
||
|
|
netmask or a CIDR prefix as well.
