Bind9 subdomain setup, why doesn't it work?

Question

Domain Name System

I tried to create a subdomain on my local dns server, I did everything as it should be:
in named.conf.local

zone "bill.microsoft.com" {
     type master;
      file "/etc/bind/db.bill.microsoft.com";

};

And correspondingly:

$TTL    604800
@       IN      SOA    bill.microsoft.com. root.bill.microsoft.com. (
                              4         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      127.0.0.1
@       IN      A       192.168.1.12
@       IN      AAAA    ::1
ns      IN      A       127.0.0.1

But for some reason the server is not found. It would seem an elementary example, but I can not understand what the problem is.

Answer 1

dig @127.0.0.1 bill.microsoft.comwhat does he say?

Answer 2

$TTL        3600

                        7200              ; refresh, seconds
                        540              ; retry, seconds
                        604800              ; expire, seconds
                        86400 )            ; minimum, seconds
