“ dig @localhost域”返回NOERROR，但“ dig domain”返回SERVFAIL

Question

我在VirtualBox上设置了一个额外的静态IP，以测试DNS服务器。

但是当我尝试对其进行测试时，出现以下问题：

dig cali.返回SERVFAIL。

dig @localhost cali.返回正确的记录。

我可能做错了什么？

绑定文件：

/etc/bind/named.conf.local

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

/etc/bind/named.conf.options

options {
        directory "/var/cache/bind";

        // If there is a firewall between you and nameservers you want
        // to talk to, you may need to fix the firewall to allow multiple
        // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.

        forwarders {
                8.8.8.8;
        };

        //========================================================================
