Hi, I have a fedora32 system with bind-9.11.25 and having a problem
with setting up a reverse zone for a 192.168.1.0/24 internal network.

It loads okay, but queries fail:

# host 192.168.1.1
Host 1.1.168.192.in-addr.arpa. not found: 3(NXDOMAIN)

Here is my /etc/named.conf zone info for the forward and reverse:

acl "trusted" {
        { 127/8; };
        { 68.195.111.40/29; };
        { 192.168.1.0/24; };
};

zone "inside.example.com." {
        type master;
        file "master/inside.example.com.db";
        forwarders {};
        allow-query { trusted; };
        allow-transfer { none; };
};

zone "0-24.1.168.192.in-addr.arpa." {
        type master;
        file "master/192.168.1.db";
        allow-query { trusted; };
        allow-transfer { none; };
};

Here is the actual zone file.
/var/named/chroot/var/named/master/192.168.1.db

$TTL 1H
$ORIGIN 0-24.1.168.192.in-addr.arpa.
@ 3600  IN      SOA     orion.inside.example.com. admin.example.com.
107 3H 1H 1W 1H
@ 3600  IN      NS      orion.inside.example.com.
@ 3600  IN      A       192.168.1.1

1       IN      PTR     orion.inside.example.com.
150     IN      PTR     pixie.inside.example.com.

What could I possibly be doing wrong? When I run dig +trace it doesn't
appear to look to the local name server, but instead goes to the
Internet and the top-level name servers.

# dig +trace any 150.1.168.192.in-addr.arpa.

Thanks,
Alex
