Помогите разобраться с настройкой зон в DNS

Имеем BIND 9.
Настраиваем его в качестве сервера имен для локальной сети и
в качестве кэша для имен интернет.
Помогите понять как настраивать файлы зон home.rev и localhost.rev. Конфиг named.conf:
--
acl "home" {192.168.0.0/24;};
options { directory "/etc/namedb";
statistics-file "named.stat";
pid-file "/var/lock/named/named.pid"; allow-query {"home";};
forwarders {195.162.32.5; 195.162.41.8;}; //адреса DNS моего провайдера.
};
zone "." {
type hint;
file "www.cache";
};
zone "0.168.192.in-addr.arpa" {
type master;
file "home.rev";
notify no;
};
zone "0.0.127.in-addr.arpa" {
type master;
file "localhost.rev";
notify no;
};
--
