绑定DNS配置没有显示域的记录

Question

我是新的DNS设置，并遵循有关设置绑定DNS的几个说明。下面是我的区域文件：

;
$TTL    604800
@       IN      SOA     sandbox.svr. root.viper.sandbox.svr. (
                              13        ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;

; Name servers

; A records for name servers

viper.sandbox.svr   IN  A       192.168.1.7
viper           IN      A       192.168.1.7


;
; BIND reverse data file for local loopback interface
;
$TTL    604800
@       IN      SOA    viper.sandbox.svr. root.sandbox.svr. (
                              11        ;Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;

; name servers - NS Records

@       IN      NS      viper.sandbox.svr.

; PTR Records
10      IN      PTR     viper.sandbox.svr.

当我跑的时候

dig sandbox.svr 

它不返回任何记录。

但当我测试时：

  dig viper.sandbox.svr

它确实返回了一条记录：

root@viper:/var/log# dig viper.sandbox.svr

; <<>> DiG 9.16.1-Ubuntu <<>> viper.sandbox.svr

我能做错什么？我的配置是一个本地环境，并运行在Ubuntu20.04桌面上。

请参阅下面的syslog输出。

我试图通过删除internet连接来排除故障，并注意到dig使用A记录进行响应，但一旦连接到意图，它就没有。是否有办法使本地查询和转发公共名称的本地 DNS解析为google dns服务器？

Answer 1

请补充：

@ IN a 192.168.1.7

然后，它将回答纯域查询，没有主机名。

谢谢,
