title: Own DNS server not working (SERVFAIL when trying to find out host's IP)
body: <p>I've set up a DNS server on VM. When I'm using <code>host</code> with an IP addres, it works well (<code>101.48.168.192.in-addr.arpa domain name pointer s1.home.lan.</code>), but when I try to get domain's IP (eg. <code>host s1.home.lan</code>), I get <code>Host s1.home.lan not found: 2(SERVFAIL)
  </code>. What has been configured wrong? </p>

          type master;

  };
  
  zone "48.168.192.in-addr.arpa" {
          type master;
          file "/etc/bind/zones/rev.48.168.192.in-addr.arpa";
