如何知道静态IP是否分配给公司或isp

Question

有没有办法知道是否为ISP分配了静态IP？我正在使用phpwhois类来查找IP所有者，但我无法找到它是公司还是ISP。有可能吗？

Answer 1

试试这个：

<?php 
$domain=$_SERVER['REMOTE_ADDR'];
$domain1 = isset($_SERVER['HTTP_X_FORWARDED_FOR']) ? $_SERVER['HTTP_X_FORWARDED_FOR'] : $_SERVER['REMOTE_ADDR'];
echo "Viewer's Server's IP Address: <strong>$domain</strong> - ";
echo "Viewer's PC IP Address: <strong>$domain1</strong>";
?>
