IPCALC(1)					RH					IPCALC(1)

NAME
       ipcalc - perform simple manipulation of IP addresses

SYNOPSIS
       ipcalc [OPTION]... <IP address>[/prefix] [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.   An	IP  address to operate on must always be specified.  Most operations also
       require a netmask or a CIDR prefix as well.

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

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

       -m, --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 net-
	      masks, in which case an inappropriate value will be returned.

       -p, --prefix
	      Show the prefix for the given mask/IP address.

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

       -s, --silent
	      Don't ever display error messages.
