DDNS for multiple zones

[Jason Gerfen]

Assuming your current client/servers are a member of a subnet group perhaps
adding the zone definition to each of this will work. Reference:
http://markembling.info/2011/10/dhcp-and-dynamic-dns

Example:

subnet 10.25.0.0 netmask 255.255.0.0 {
    range 10.25.10.1 10.25.10.254;
    option routers 10.25.1.1;

    zone 25.10.in-addr.arpa. {
        primary 10.25.2.4;
        key "rndc-key";
    }

    zone home.markembling.info. {
        primary 10.25.2.4;
        key "rndc-key";
    }
}


In regards to not setting a default option within the global parameters
this may be by design.
