1. I guess you didn't know there is ++ operator? :) You can write your code $ip[3] = $ip[3] + 1; as $ip[3]++

2. Do you know you can call function with splices? func($arr[0], $arr[1], $arr[2], $arr[3]) is the same as func(@arr[0..3]);

3. Your function nextIp() would be two/three lines long if you operated on simple 32-bit int, passed 32-bit int to ping() function and there converted to IP like this:

$ip = $_[0]; # your 32-bit int
$arr[3] = $ip & 255;
$ip >>= 8;
$arr[2] = $ip & 255;
$ip >>= 8;
$arr[1] = $ip & 255;
$ip >>= 8;
$arr[0] = $ip & 255;
