Sys::HostIP3pm

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 => {...} );

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.
