I can't stop clients from making certain kinds of queries (unless BIND has a feature to refuse such queries or not recurse for them?). Whenever a client makes the 'ANY' query, it effectively causes a DoS on that name. Luckily the MinTTL is only 30 seconds, so the problem goes away after 30 seconds.
This is a fair point. TBH I wonder if bind mightn't be better caching ANY as a separate pseudo-type, if I'm understanding the problem correctly.
