DNS-сервер несколько доменов обратный

Question

Я настроил DNS-сервер в Debian Jessy, я настраиваю домены, но не работает должным образом. Мои файлы конфигурации:

ФАЙЛ named.conf.local

include "/etc/bind/named.conf.log";
//uno
//directa

zone "uno.com.ar" IN {
    type master;
    file "/etc/bind/uno.com.ar";
    allow-query { any; };
};

//reversa
zone "100.43.200.in-addr.arpa" {
    type master;
    file "/etc/bind/uno.com.ar.reversa";
};


zone "dos.com.ar" IN {
    type master;
    file "/etc/bind/dos.com.ar";
    allow-query { any; };
};
