ACL in /etc/named.zones

[Sim]

Hi to All!

Is it possible to substitute all "masters {192.168.2.7; 192.168.2.8};"
with ACL ?

Source :
------------------------------------------------------------------
zone "example.com" in {
    type slave;
    file "slave.example.com";
    masters { 192.168.2.7; 192.168.2.8; };
};



For example:
------------------------------------------------------------------
acl masters {
        89.186.33.2;
};

zone "example.com" in {
    type slave;
    file "slave.example.com";
    masters { masters; };
};


Thanks

Sim
