i'm using the below perl code to get a list of ips:

heap::elem::num
Heap::Elem::Num(3pm) User Contributed Perl Documentation Heap::Elem::Num(3pm)NAME
Heap::Elem::Num - Numeric Heap Elements
SYNOPSIS
use Heap::Elem::Num( NumElem );
use Heap::Fibonacci;
my $heap = Heap::Fibonacci->new;
my $elem;
foreach $i ( 1..100 ) {
$elem = NumElem( $i );
$heap->add( $elem );
}
while( defined( $elem = $heap->extract_top ) ) {
print "Smallest is ", $elem->val, "
";
}
DESCRIPTION
Heap::Elem::Num is used to wrap numeric values into an element that can be managed on a heap. The top of the heap will have the smallest
element still remaining. (See Heap::Elem::NumRev if you want the heap to always return the largest element.)
The details of the Elem interface are described in Heap::Elem.
The details of using a Heap interface are described in Heap.
