智能DNS的配置主要修改named.conf文件，利用view和acl来实现。
acl文件内容,这里只列出一部分，具体详细的可以参考这个网址
纯真IP库，给出了十分详细的IP地址，下载安装后，打开软件，点击解压就可以获取到txt文本格式的IP地址

IP转换为acl工具下载地址
http://blog.lishixin.net/linux/468.html/attachment/dnstool
按照下面博客中的步骤将IP转换为acl格式
http://blog.lishixin.net/archives/468#more-468
注意事项：
只要配置了view的时候，所有的zone都必须包含到view中。
包括下面的这两行
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
下面是本配置中需要的，只列出部分IP的acl文件，这个不影响正常使用
mkdir -p /var/named/acl/srcip/
vim /var/named/acl/srcip/AnHui.acl
acl "AnHui.cnc"{
36.32.0.0/;
