自动dns客户端在绑定服务器上注册

我已经配置了2个绑定服务器作为主和从。一开始，我手动添加了5个客户端记录在正向和反向区域，它工作得很完美。然而，我需要在绑定服务器上自动注册新客户端，而不是手动像微软DNS服务器。我的配置文件如下:

主服务器:

        listen-on port 53 { 127.0.0.1; 192.168.120.128; };
        ...
        allow-query     { localhost; 192.168.120.0/24; };
        allow-transfer  {192.168.120.129; };
        ...
zone"test.local" IN {
type master;
file "testlocal.fwd.zone";
update-policy {
 grant update-key name test.local A;
 };
};
zone"120.168.192.in-addr.arpa" IN {
type master;
file "testlocal.rev.zone";
update-policy {
 grant update-key name test.local A;
 };
};

从服务器:

        listen-on port 53 { 127.0.0.1; 192.168.120.129; };
        ...
        allow-query     { localhost; 192.168.120.0/24; };
zone"test.local" IN {
type slave;
file "slaves/testlocal.fwd.zone";
masters { 192.168.120.128; };
};
zone"120.168.192.in-addr.arpa" IN {
type slave;
file "slaves/testlocal.rev.zone";
masters { 192.168.120.128; };
};
