NAME
    Sys::HostIP - Try extra hard to get IP address related info

VERSION
    version 1.97

SYNOPSIS
        use Sys::HostIP;

        my $hostip     = Sys::HostIP->new;
        my $ips        = $hostip->ips;
        my $interfaces = $hostip->interfaces;

DESCRIPTION
    Sys::HostIP does what it can to determine the ip address of your
    machine. All 3 methods work fine on every system that I've been able to
    test on. (Irix, OpenBSD, FreeBSD, NetBSD, Solaris, Linux, OSX, Win32,
    Cygwin). It does this by parsing ifconfig(8) (ipconfig on Win32/Cygwin)
    output.

    It has an object oriented interface and a functional one for
    compatibility with older versions.

ATTRIBUTES
  ifconfig
        my $hostip = Sys::HostIP->new( ifconfig => '/path/to/your/ifconfig' );

    You can set the location of ifconfig with this attribute if the code
    doesn't know where your ifconfig lives.

    If you use the object oriented interface, this value is cached.

  if_info
    The interface information. This is either created on new, or you can
    create it yourself at initialize.

        # get the cached if_info
        my $if_info = $hostip->if_info;

        # create custom one at initialize
        my $hostip = Sys::HostIP->new( if_info => {...} );

METHODS
  ip
        my $ip = $hostip->ip;

    Returns a scalar containing a best guess of your host machine's IP
    address. On *nix (Unix, BSD, GNU/Linux, OSX, etc.) systems, it will
    return the loopback interface (127.0.0.1) if it can't find anything
    else.

  ips
        my $all_ips = $hostip->ips;
        foreach my $ip ( @{$all_ips} ) {
            print "IP: $ip\n";
        }

    Returns an array ref containing all the IP addresses of your machine.

  interfaces
        my $interfaces = $hostip->interfaces;

        foreach my $interface ( keys %{$interfaces} ) {
            my $ip = $interfaces->{$interface};
            print "$interface => $ip\n";
        }

    Returns a hash ref containing all pairs of interfaces and their
    corresponding IP addresses Sys::HostIP could find on your machine.

  EXPORT
    Nothing by default!

    To export something explicitly, use the syntax: Nothing.

        use HostIP qw/ip ips interfaces/;
        # that will get you those three subroutines, for example

    All of these subroutines will match the object oriented interface
    methods.

    *   ip

    *   ips

            my $ips = ips();

    *   interfaces

TODO
    I haven't tested the win32 code with dialup or wireless connections.

    Machines with output in different languages (German, for example) fail.
