Caio,


####   VOCÊ DECLAROU 
zone "79.168.192.in-addr.arp" {
       type master;
       file "/etc/bind/db.79.168.192.in-addr.arpa";
};


#### CORRETO
zone "79.168.192.in-addr.arpa" {
       type master;
       file "/etc/bind/db.79.168.192.in-addr.arpa";
};


Faltou um a no addr.arp(aqui)


De qualquer forma, depois de fazer a alteração, verifique a saida do [named] no log.
