I want to build a server at home and in order to serve subdomains I have to offer a DNS service. After several attempts and having followed many tutorials, I still have not been able to accomplish it. This is my configuration:

• LAN is 192.168.178.0/24
  


• server's hostname is zotac and it's IP is 192.168.178.10
  


• The domain's name should be spiti
  


• The subdomains should be reached by typing financer.spiti, fotos.spiti, wiki.spiti and so on in the browser from any device in the LAN


• 
  bind9 is installed and running on zotac
  


• 
  named-checkconf /etc/bind/named.conf throws no errors

Configuration files:

/etc/bind/named.conf.local

zone "spiti" {

        type master;

        file "/etc/bind/db.spiti";

};



zone "178.168.192.in-addr.arpa" {

        type master;

        notify no;

        file "/etc/bind/db.178.168.192";

};

/etc/bind/named.conf.options

options {

        directory "/var/cache/bind";

        forwarders {

                1.1.1.1;

                1.0.0.1;

        };

        dnssec-validation auto;



        auth-nxdomain no;    # conform to RFC1035

        listen-on-v6 { any; };

};

Zone "spiti":/etc/bind/db.spiti

10      IN      PTR     fotopoulos.spiti.

10      IN      PTR     spiti.

• 
  curl zotac returns the index.html content under the apache home folder: ok.


• 
  curl spiti returns Could not resolve host: spiti : not ok


• When I configure my modem-router to use my server as DNS server, no device has connection to internet.

What am I doing wrong?

@grawity , thanks for the tool, I did not know it. Unfortunately, I have no other ubuntu machine in the LAN, but if I do it from zotac, I get following:
