dns-view （分网段智能解析）

对传统dns而言，添加了acl和view，可使不同的ip或网段解析同一域名得出不同的结果，在安全上和负载均衡上能起到一定的作用

                    file "192.168.1.10.arpa";
                   
};

};

view external {
       matchclients {!192.168.1.10;192.168.1.12;};            (不用1.10解析，用1.12解析)
      zone "yang.com" IN {
                    type master;
                    file "ming.com.zone";

  zone "12.1.168.192.in-addr.arpa" IN {
