服务器找不到 example.com：NXDOMAIN

Question

我在设置具有正向和反向区域的本地 DNS 服务器时遇到了麻烦。

解析配置文件

search myco.nmm6145.com
nameserver 192.168.1.1
nameserver 192.168.1.2

命名配置文件

options {
    directory "/var/named";
    listen-on port 53 {any;};
    allow-query {localhost;};
    allow-transfer {any;};
    empty-zones-enable no;
    recursion yes;
    dnssec-enable yes;
    dnssec-validation yes;
    bindkeys-file "/etc/named.root.key";
    managed-keys-directory "/var/named/dynamic";
    pid-file "/run/named/named.pid";
    session-keyfile "/run/named/session.key";
};

zone "."            { type hint;    file "named.ca";    allow-query {any;};};
zone "0.0.127.in-addr.arpa."    { type master;  file "db.127.0.0";  allow-query{any;};};
zone "myco.nmm6145.com"     { type master;  file "db.myco";     allow-query{any;};};
zone "1.168.192.in-addr.arpa."  { type master;  file "db.192.168.1"; };
zone "20.168.192.in-addr.arpa." { type master;  file "db.192.168.20"; };

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

以下是我为诊断问题而运行的一些命令：

nslookup @localhost linserv.myco.nmm6145.com

;;Got SERVFAIL reply from 192.168.122.1, trying next server

不确定 122 子网在这里发挥作用，似乎无法在我的任何区域或配置文件中找到它。
