Reverse DNS Slave Setup

So a few months back, I enabled reverse DNS on my home BIND server (https://www.rubysecurity.org/bind_rerverse-dns). One thing that I forgot to implement was the additional slave DNS reverse setup. Like many things in BIND, the slave revserse DNS setup was dead simple.

It's simply just a matter of adding the following entry to the slave's named.conf with the updated master's DNS IP specified in the masters directive and reload BIND.

zone "1.168.192.in-addr.arpa" IN {
        type slave;
        file "etc/zones/db.192.168.1.255.bak";
        allow-query { any; };
        masters { MasterDNSIP; };
};
