ipcalc [OPTION]... <IP address>[/prefix] [netmask]
ipcalc provides a simple way to calculate IP information for a host. The various options specify what information ipcalc 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.
