I'm curious why you felt the need to double this.

I don't like to blackhole IP at layer 7, this belongs in the
routers IMHO, but you might regard it as security in depth, it
is a judgement call.

auth-nxdomain no; //gets rid of irritating nag message!

I don't mix authoritative and caching where I can avoid it,
should additional-from-cache be "no" in such cases?

You have some options for controlling/restricting "silly" SOA
record values from the masters you slave, I don't have much
practical experience with these settings, but sound like they
may have save you grief! (or create grief) min-refresh-time etc.

We don't know what zones your handling but we assume you did
good with (and kill spurious traffic to, and other RFC1918 space).
