A proxy regex ?

https://www.experts-exchange.com/questions/22050007/stipping-out-proxy-list-from-web-using-php.html

I have read this topic about how to use regex to strip out proxies from a page. Here is the final code by TeRReF :

<?php

$s = '80.249.72.180:80          elite proxy          Algeria (Algiers)
80.249.76.82:80          anonymous          Algeria
190.49.168.251:6588          elite proxy          Argentina (Buenos Aires)
83.160.170.10      8080      transparent      Netherlands      2006-10-25      Whois
203.106.52.102      3128      transparent      Malaysia      2006-10-25      Whois
213.52.140.53      80      anonymous      Great Britain (UK)      2006-10-25      Whois
128.134.137.23:8080 3 Kb/s
138.89.253.5:33322 26 Kb/s
192.38.109.143:3128 23 Kb/s
165.228.131.10      3128      transparent      Australia      2006-10-25      Whois
212.174.34.186      8080      anonymous      Turkey      2006-10-25      Whois
1      202.147.181.2      8080      transparent      Pakistan      2006-11-05      WHOIS
2      62.101.80.187      8080      high anonymity      Italy      2006-11-05      WHOIS
3      84.20.143.8      8080      transparent      Finland      2006-11-05      WHOIS
4      203.115.1.135      80      transparent      Sri Lanka      2006-11-05      WHOIS
yoho.uwaterloo.ca:8000   transparent      Pakistan      2006-11-05      WHOIS
kleinbonum.ethz.ch:8000   elite proxy          Algeria (Algiers)';

preg_match_all('/([\w\d]+\.[\w\d\.]+)[:\s]+(\d{1,5})/i', $s, $matches);
$count = count($matches[1]);
for ($i = 0; $i < $count; $i++)
        $lines[] = $matches[1][$i].':'.$matches[2][$i];

print_r($lines);

?>

It works well with the strings inside the $s but if the are something like abcdef255.255.255.255:80 then the code will go wrong. Can anyone provide an update for this please ? All helps will be appreciated. Thanks.
