If you're running bind for your recursive boxes, `rndc -s <server>
flushname <zone>' run against each recursive box should do the trick
for bind 9.3.0 upwards. It will flush the cache for that zone only.
There was a bug where it wouldn't flush negative caches, but that
might be fixed. YMMV, etc.
Usual common sense warnings apply.
