how to configure BIND to be stong to attacks and keep them from using

We do such on our authoritative nameservers. The options we use:
listen-on { 127.0.0.1; 72.20.106.4; };
query-source address 72.20.106.4;
transfer-source 72.20.106.4;
notify-source 72.20.106.4;
interface-interval 0;
use-alt-transfer-source no;
Have you found those -source options to be necessary in practice? In
general named should be smart enough not to try reaching the outside
world on the loopback address.
Also, I'm guessing that you have more than one public IP address
configured on that box? Otherwise none of those options should be
necessary.
