IP反向查询工具

现在国内使用wordpress的用户不少，很多采用自建博客后租用虚拟空间，那么空间的服务就很重要，这里介绍一个简单的IP反向查询工具，帮助大家了解一下自己的服务器上同一IP有多少个域名，也就可以了解你的hosting供应商有多黑了。

查询同一IP下不同域名：
$ip=trim($_POST['ip']);
if(!empty($ip) && !eregi("([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})",$ip)){
echo "IP地址格式不正确!请重新输入“;
$ip=”";
}
?>

if (!empty($ip)){
include "Snoopy.class.php";
$snoopy = new Snoopy ( );
$snoopy->agent = “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)”;
$snoopy->rawheaders ["Pragma"] = “no-cache”;
$snoopy->expandlinks = true;
$refer = “http://www.domaintools.com/reverse-ip/”;
$snoopy->cookies["nisession"] = ‘w4yyoBRKlMOaEuWxuw4mxc9agwAlZGPRjKbzJKmFStw%253D’;
$snoopy->referer = $refer;
//$snoopy->user = “joe”;
//$snoopy->pass = “bloe”;
//$snoopy->rawheaders["X_FORWARDED_FOR"] = “127.0.0.101″;
$snoopy->rawheaders["X-Requested-With"] = “XMLHttpRequest”;

$submit_url = “http://www.domaintools.com/reverse-ip/functions.html?s=preview”;

$submit_vars ["ip"] = $ip;
$submit_vars ["_"] = “”;

if ($snoopy->submit ( $submit_url, $submit_vars )) {
preg_match ( “/

“;
foreach ( $art_list as $art_node ) {
$tmp=trim($art_node);
if (!empty($tmp))
echo “
• “. $art_node .”

“;
}
echo “

“;
} else
echo “error fetching document: ” . $snoopy->error . “\n”;
}//end of if empty ip
?>

你也可以使用如下IP反向查询多个域名的工具

如果你用的是虚拟主机，要注意防范旁注攻击。
