I have a local dns server (bind 9), and I wonder if there is some

I don't know about bind, but I doubt you could filter it at the
firewall, as you'd then have to filter all DNS requests.
Not necessarily - iptables has content inspection, so it might be
possible to identify individual AAAA queries. The question is if
dropping such queries wouldn't just mean longer processing time?
