-.TH IPCALC 1 "April 30 2001" "Red Hat, Inc." \" -*- nroff -*-
-.SH NAME
-ipcalc \- perform simple manipulation of IP addresses
-.SH SYNOPSIS
-.B ipcalc
-[\fIOPTION\fR]... <\fBIP address\fR>[\fI/prefix\fR] [\fInetmask\fR]
-
-.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.
-
-.SH OPTIONS
-.TP
-.TP
-\fB\-c\fR, \fB\-\-check\fR
-Validate the IP address under the specified family.  If no address
-family is specified, IPv4 is assumed.
-
-.TP
-\fB\-4\fR, \fB\-\-ipv4\fR
-Specify IPv4 address family (default).
-
-.TP
-\fB\-6\fR, \fB\-\-ipv6\fR
-Specify IPv6 address family.
-
-.TP
-\fB\-b\fR, \fB\-\-broadcast\fR
-Display the broadcast address for the given IP address and netmask.
-
-.TP
-\fB\-h\fR, \fB\-\-hostname\fR
-Display the hostname for the given IP address.
-
-.TP
-\fB\-m\fR, \fB\-\-netmask\fR
-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.
-
-.TP
-\fB\-p\fR, \fB\-\-prefix\fR
-Show the prefix for the given mask/IP address.
-
-.TP
-\fB\-n\fR, \fB\-\-network\fR 
-Display the network address for the given IP address and netmask.
-
-.TP
-\fB\-s\fR, \fB\-\-silent\fR 
-Don't ever display error messages.

-  \file ipcalc.c
-  \brief provides utilities for manipulating IP addresses.
-
-  ipcalc provides utilities and a front-end command line interface for
-  manipulating IP addresses, and calculating various aspects of an ip
-  address/netmask/network address/prefix/etc.
-
-  Functionality can be accessed from other languages from the library
-  interface, documented here.  To use ipcalc from the shell, read the
-  ipcalc(1) manual page.
-
-  When passing parameters to the various functions, take note of whether they
-  take host byte order or network byte order.  Most take host byte order, and
-  return host byte order, but there are some exceptions.
