文章底部有关于使用KoolProxy过滤视频广告iPSet工作CPU占用高解决方法

iptables只能根据ip地址进行转发，不能识别域名，而Dnsmasq-full不仅可以实现域名-IP的映射，还可以把这个映射关系存储在iPSet中，所以使用dnsmasq+ipset就可以实现iptables对域名的转发，可以实现很多功能

原理很简单，就是Dnsmasq接收到一个DNS查询请求，首先匹配配置文件中的域名列表，如果匹配成功某域名，就把IP的查询结果存储在一个或几个ipset集合中，然后使用iptables对这个ipset中的全部ip进行匹配并做相应的处理，如DROP或者REDIRECT或者设置mark

Dnsmasq+ipset+iptables基于域名的流量管理:

iptables -t mangle -I PREROUTING -m set --match-set wechat dst -j DROP
iptables -t mangle -D PREROUTING -m set --match-set wechat dst -j DROP
iptables -t mangle -I PREROUTING -m set --match-set video dst -j DROP
iptables -t mangle -D PREROUTING -m set --match-set video dst -j DROP
