NAME

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

VERSION

version 1.90

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.

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_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 $interface ( @{$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.

This module is completely Object Oriented.

TODO

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

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