DNS 请求状态：SERVFAIL

DNS 请求状态：SERVFAIL

你能看看下面的配置以及我做错了什么吗？

刚刚设置了 Ubuntu 14.04.4 LTS 并绑定，当我挖掘我的服务器时，我得到了一个状态：SERVFAIL

我的配置如下：

dig @192.168.6.1 www.example.com

; <<>> DiG 9.9.6-P2 <<>> @192.168.6.1 www.example.com
; (1 server found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 25376
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1

;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 4096
;; QUESTION SECTION:
;www.example.com.                        IN      A

;; WHEN: Fri Jun 10 12:13:28 UTC 2016
;; MSG SIZE  rcvd: 43

named.conf.local包含

 zone "example.com" {
         type master;
         file "/etc/bind/db.example.com";
    };

 zone "128.10.in-addr.arpa" {
   type master;
   file "/etc/bind/db.192.168";  # 192.168.0.0/16 subnet
  };

named.conf.options

options {
      directory "/var/cache/bind";
    recursion yes;                 # enables resursive queries
    allow-recursion { any; };  # allows recursive queries from "trusted" clients
    listen-on { 192.168.6.1; };   # ns1 private IP address - listen on private
    allow-transfer { none; };
    allow-query { any; };
    forwarders {
            8.8.8.8;
            8.8.4.4;
    };
    auth-nxdomain no;    # conform to RFC1035
    listen-on-v6 { any; };
  };

错误出现在以下行：@ IN SOA ns.example.com. root.example.com。不要使用上面的代码，而要使用：@ IN SOA 例如.com。root.example.com。
