BIND 8 以上的 DNS （NT 4 亦可）可以設定無法 Dump Zone；可以參考O reilly BIND and DNS 第十章談 DNS Security 部分（第 249 頁開始）以下為相關之 BIND Options 範例：

Restricting all queries:

options {
allow-query { 192.168.1/24; 192.168.2/24; };
};


Restricting queries in a particular zone:

zone "hp.com" {
type slave;
file "hp.com.zone"
masters {192.168.1.1; };
allow-query { 192.168/16; };
};


Preventing Unauthorized Zone Transfers:

zone "ibm.com" {
type master;
file "ibm.com.zone";
allow-transfer { 192.168.1.1; 192.168.1.2; };
};
