Centos 7 bind gibt nichts zurück

Ich habe versucht, einen DNS-Server zu bilden, aber wenn ich den dig-Befehl mache, gibt der Server nichts zurück. Ich habe noch keine Erfahrungen gemacht und folge nur diesem Tutorial: http://www.itzgeek.com/how-tos/linux/centos-how-tos/configure-dns-bind-server-on-centos-7- rhel-7.html .

named.conf-Datei:

Failing to do so will cause your server to become part of large scale DNS amplification attacks. Implementing BCP38 within your network would greatly reduce such attack surface */ recursion yes;  dnssec-enable yes; dnssec-validation yes; dnssec-lookaside auto;  /* Path to ISC DLV key */ bindkeys-file "/etc/named.iscdlv.key";  managed-keys-directory "/var/named/dynamic";  pid-file "/run/named/named.pid"; session-keyfile "/run/named/session.key"; };  logging { channel default_debug { file "data/named.run"; severity dynamic; }; };  zone "."

Update: Es sieht so aus, als ob das Problem bei /etc/resolv.confjedem Neustart des Netzwerk-Managers überschrieben wird. Ich werde dies später erneut aktualisieren, wenn ich die if-cfg-Datei erhalten kann.
