You have to
  1. get the start and end values, 
    my($min, $max) = /\b([0-9a-f]+):([0-9a-f]+)\b/i;

    [download]
  2. convert them to integers 
    foreach($min, $max) {
    $_ = hex($_);
}

    [download]
  3. turn them into a range or span: 
    my @list = $min .. $max;

    [download]
  4. turn each into a hex number. 
    my @hex = map { sprintf '%X', $_ } $min .. $max;

    [download]
    will do.
  5. print out the list with ',' between them: 
    $, = ','; print @list;

    [download]
     update Oops, that should have been 
    $, = ','; print @hex;
