**注意：**  
如域名使用了云加速，则以下方法均失效，需在云加速中添加IP黑名单。

方法一：页面后缀必须为.php

<?php
    	//获取用户IP地址
    	if($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]){
      		$key = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"];
    	}elseif($HTTP_SERVER_VARS["HTTP_CLIENT_IP"]){
      		$key = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"];
    	}elseif($HTTP_SERVER_VARS["REMOTE_ADDR"]){
      		$key = $HTTP_SERVER_VARS["REMOTE_ADDR"];
    	}elseif(getenv("HTTP_X_FORWARDED_FOR")){
      		$key = getenv("HTTP_X_FORWARDED_FOR");
    	}elseif (getenv("HTTP_CLIENT_IP")){
      		$key = getenv("HTTP_CLIENT_IP");
    	}elseif (getenv("REMOTE_ADDR")){
      		$key = getenv("REMOTE_ADDR");
    	}else{
      		$key = "Unknown";
    	}
    	//被屏蔽的IP
    	$ip_list=array(
    		'101.229.247.204'
    	);
    	if(in_array($key,$ip_list)){
    		echo "网站维护中...";
    		exit();
    	}
    ?>

方法二：在服务器IIS中选择需要屏蔽的站点进行以下操作即可，无需重启IIS。

方法三：在网站根目录下添加.htaccess文件，文件添加以下代码即可。  
禁止指定IP地址：如：192.168.1.1  
order Deny,Allow  
deny from 192.168.1.1  
deny from 117.71.61.221  
禁止指定IP地址段：  
order Deny,Allow  
deny from 192.168.1-192.168.1.254
