    介绍

由于GFW的域名黑名单是不断变化的，如果所有DNS查询都走VPN会丧失CDN加速功能，经常出现本地电信线路，但是却访问网站的联通线路，而且当VPN线路不稳定的时候，会影响所有网站的访问。如果使用域名白名单或黑名单，对于经常访问外国网站的用户，体验很不好，需要用户自己维护域名列表。
该文章介绍如何通过判断并丢弃包含特征IP的DNS包来防止DNS污染，但是又不会失去本地DNS的CDN加速功能，而且还不需要VPN。
前期准备


一台Openwrt路由器
使用dnsmasq作为Openwrt的dns服务器
安装 dig (opkg install bind-dig bind-libs)
安装 iptables 的 string 模块及对应的内核模块 (opkg install iptables-mod-filter kmod-ipt-filter)
