标题: 域名解析要试好几次才能返回正确结果
as4自带的rpm包装的bind,申请好了ns服务器，在本机cmd下测试域名，要ping好几次才能返回正确的IP，用nslookup测试域名的ns，也是这样，刷新几次才返回出结果，请问这大概是哪方面的问题，named.conf配置如下
//
// named.conf for Red Hat caching-nameserver

options {
      allow-transfer {
//Default: DisAllow all zone-transfer
//You can add the slave dns server's ip below to allow zone-transfer between master & slave server
//Example:
//    192.168.200.131;

      };
//Hidden the version
      version "unknown";
      directory "/var/named";
      dump-file "/var/named/data/cache_dump.db";
      statistics-file "/var/named/data/named_stats.txt";
      /*
      * If there is a firewall between you and nameservers you want
      * to talk to, you might need to uncomment the query-source
      * directive below.  Previous versions of BIND always asked
      * questions using port 53, but BIND 8.1 uses an unprivileged
      * port by default.
      */
      // query-source address * port 53;
};

//
// a caching only nameserver config
//
controls {
      inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};

zone "." IN {
      type hint;
      file "named.ca";
};

zone "localdomain" IN {
      type master;
      file "localdomain.zone";
      allow-update { none; };
};

zone "localhost" IN {
      type master;
      file "localhost.zone";
      allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
      type master;
      file "named.local";
      allow-update { none; };
};

zone "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
      type master;
      file "named.ip6.local";
      allow-update { none; };
};

zone "255.in-addr.arpa" IN {
      type master;
      file "named.broadcast";
      allow-update { none; };
};

zone "0.in-addr.arpa" IN {
      type master;
      file "named.zero";
      allow-update { none; };
};

include "/etc/rndc.key";

还有运行dig -t ns .怎么只有一个ns的IP能出来
[root@mail ~]# dig -t ns .

; <<>> DiG 9.2.4 <<>> -t ns .

请问这大概是哪方面的问题，是我dns不正常，还是授权有问题
