如何禁止大量的IP范围？

标签： php .htaccess block detect googlebot

我如何检测Google，不仅仅是抓取工具，我的意思是一般。

根据this site，以下IP地址范围属于Google：

64.233.160.0 - 64.233.191.255
66.102.0.0 - 66.102.15.255
66.249.64.0 - 66.249.95.255
72.14.192.0 - 72.14.255.255
74.125.0.0 - 74.125.255.255
209.85.128.0 - 209.85.255.255
216.239.32.0 - 216.239.63.255

（这些是否真的都是他们的IP地址？）

有没有一种简单的方法可以使用PHP或.htaccess从我的网站上禁止所有这些数百个IP？我的意思是另一种方式：

$ip = $_SERVER['REMOTE_ADDR'];
if $ip == "64.233.160.0" || $ip = "64.233.160.1" ...) 
   //...

可以适应数据库加载范围的PHP实现如下所示：

<?php

$ranges = [
    ['64.233.160.0', '64.233.191.255'],
    ['66.102.0.0'  , '66.102.15.255' ],
    ['66.249.64.0' , '66.249.95.255' ],
    ['72.14.192.0' , '72.14.255.255' ],
    ['74.125.0.0'  , '74.125.255.255'],
    ['209.85.128.0', '209.85.255.255'],
    ['216.239.32.0', '216.239.63.255']
];

function in_range($ip, $ranges) {
    $size = count($ranges);
    $longIP = ip2long($ip);
    for ($i = 0; $i < $size; $i++)
        if ($longIP >= ip2long($ranges[$i][0]) && $longIP <= ip2long($ranges[$i][1]))
            return true;
    return false;
}

var_dump(in_range('64.233.160.168', $ranges));
var_dump(in_range('123.123.123.123', $ranges));

Output：

bool(true)
bool(false)

是的，你可以通过将它添加到.htaccess文件或httpd.conf来实现。

这是如何阻止范围的示例。我在旧网站上使用过它。
