VERSION
version 1.97SYNOPSIS
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.

TODO
I haven't tested the win32 code with dialup or wireless connections.Machines with output in different languages (German, for example) fail.
