DDNS on DHCP Server and NAMED

[ivan1970]

we need help to enable dynamic DNS update when DHCP Server assign an IP address on a windows client.
DHCP correctly assign IP Address on client but no update is sent to dns server (named).
I have a Rocky Linux 9.2

this is my dhcpd.con file

default-lease-time 21600;
max-lease-time 86400;

authoritative;
option domain-name "example.com";
option domain-name-servers 192.168.1.1;

include "/etc/rndc.key";


server-identifier       192.18.1.1;
ddns-domainname         "example.com";
ddns-rev-domainname     "in-addr.arpa";
ddns-update-style       interim;
ddns-updates            on;
#ignore                  client-updates;



subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.50 192.168.1.250;
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;


zone  1.168.192.in-addr.arpa. {
        primary 192.168.1.1;
        key rndc-key;
}

zone example.com. {
    primary 192.168.1.1;
    key rndc-key;
}
}

this is my named.conf file
