注：根据需求修改(8.8.4.4|8.8.8.)ip范围

Linux下 规则文件.htaccess(手工创建.htaccess文件到站点根目录)
<IfModule mod_rewrite.c>
RewriteEngine On
#Block ip
RewriteCond %{http:X-Forwarded-For}&%{REMOTE_ADDR} (8.8.4.4|8.8.8.) [NC]
RewriteRule (.*) - [F]
</IfModule>

windows2003下 规则文件httpd.conf　　　（在虚拟主机控制面板中用 “ISAPI筛选器自定义设置 " 开启自定义伪静态 Isapi_Rewite3.1 ）
#Block ip
RewriteCond %{HTTP_X_FORWARDED_FOR}&%{REMOTE_ADDR} (8.8.4.4|8.8.8.) [NC]
RewriteRule (.*) - [F]

windows2008下 规则文件web.config (手工创建web.config文件到站点根目录)
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="band ip" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAny">
