IPCALC(1)

NAME
       ipcalc - perform simple manipulation of IP addresses

SYNOPSIS
       ipcalc  [--hostname] [--broadcast] [--network] [--netmask]
       ip [netmask]

DESCRIPTION
       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.

OPTIONS
       --broadcast
              Display  the  broadcast  address  for  the given IP
              address and netmask.

       --hostname
              Display the hostname for the given IP address.

       --netmask
              Calculate the netmask for the given IP address.  It
              assumes  that the IP address is in a complete Class
              A, B, or C network. Many networks do  not  use  the
              default  netmasks,  in  which case an inappropriate
              value will be returned.

       --network
              Display  the  network  address  for  the  given  IP
              address and netmask.
