How to configure dns for subnets in Ubuntu LTS 18.04 using bind9?

I need to configure a DNS to the next network design:

172.0.0.2 DHCP.technology.com

172.0.0.3 DNS.technology.com

172.0.1.0 DB1.technology.com

172.0.2.0 APP1.technology.com

I have this configuration:

named.conf.local

zone "technology.com" IN {

type master;

file "/etc/bind/forward.technology.com";

};





zone "0.0.172.in-addr.arpa" IN {

type master;

file "/etc/bind/reverse.technology.com";

};

forward.technology.com

; BIND data file for local loopback interface

    ;

    $TTL    604800

    @   IN  SOA dns.technology.com. root.dns.technology.com. (

                      2     ; Serial

                 604800     ; Refresh

                  86400     ; Retry

                2419200     ; Expire

                 604800 )   ; Negative Cache TTL

    ;

    @   IN  NS  dns.technology.com.

    @   IN  A   172.0.0.3

    dns     IN  A   172.0.0.3

    dhcp    IN  A   172.0.0.2

    db1     IN  A   172.0.1.0

    app1    IN  A   172.0.2.0

My problem is:

how can i add the db1 and app1 reverse to the reverse configuration?.

Because i added twice a 0 for an PTR (db1 and app1), this is my file:

reverse.technology.com

    ; BIND data file for local loopback interface

    ;

    $TTL    604800

    @   IN  SOA dns.technology.com. root.dns.technology.com. (

                      2     ; Serial

                 604800     ; Refresh

                  86400     ; Retry

                2419200     ; Expire

                 604800 )   ; Negative Cache TTL

    ;

    @   IN  NS  dns.technology.com.

    @   IN  PTR technology.com.

    dns     IN  A   172.0.0.3

    dhcp    IN  A   172.0.0.2

    db1     IN  A   172.0.1.0

    app1    IN  A   172.0.2.0 

    3       IN  PTR dns.example.com.

    2       IN  PTR dhcp.example.com. 

    0       IN  PTR db1.technology.com.

    0       IN  PTR app1.technology.com.
