$str = '
www.l.google.com. 272 IN A 74.125.153.104
www.l.google.com. 272 IN A 74.125.153.105
www.l.google.com. 272 IN A 74.125.153.106
www.l.google.com. 272 IN A 74.125.153.147
www.l.google.com. 272 IN A 74.125.153.99
www.l.google.com. 272 IN A 74.125.153.103
';
preg_match_all('/\s+([\d]+)[^\d]+([\d\.]+)/sim', $str, $match);
echo '<pre>';
print_r($match);
echo '</pre>';
===============> 結果 <===============
