BIND 9 主控未回复附加部分

Question

我们在 NAT 后面的 Windows Server 2008 R2 上运行 ISC BIND 9.14.3 64 位。它是主服务器。有三个外包的从属服务器（不知道运行的是什么 DNS 软件）。从属服务器甚至为区域外的记录返回额外的部分，但 BIND 主服务器没有。

named.conf 中的选项包括：

options {
  directory "c:\named";
  listen-on port 5353 { 192.168.4.12; };
  listen-on-v6 { none; };
  allow-query { any; };
  pid-file "etc\named.pid";
  recursion no;
  masterfile-format text;
  rrset-order { class IN type ANY name "*" order cyclic; };
  minimal-responses no;
  additional-from-auth yes;
  additional-from-cache yes;
};

使用dig查询主服务器不会返回附加部分：

使用dig查询任何辅助确实会返回额外的部分：

named.conf我不知道为了获得带有附加部分的响应，必须在 BIND 中做哪些其他配置。
