my forward zone configuration

[Gian]

hi,
i've still confuse about forward zone, so i wanna attach my configuration
for some to correct this conf 
in named.conf, db.hisdomain.com, db.iphisdomain.com

named.conf
---------
zone "10.10.10.IN-ADDR.ARPA" {
        type master;
        file "db.iphisdomain.com";
        allow-query {
                any;
        };
        allow-transfer {
                localhost;
                my-ns;
        };
};

zone "hisdomain.com" {
        type master;
        file "db.hisdomain.com";
        forward only;
        forwarders { 10.10.10.3; 
                     10.10.10.4;
                   };
};
