Anyway to rate-limit incoming DNS requests?[Scanned]

Hi BIND gurus,
Is there any way to configure BIND to sort of rate limit the number of DNS requests coming in from any particular IP automatically? Say, something like if I wanted to set so that any IP from the 10.10.10.0/24 subnet can only do 10 DNS requests / sec? I've been facing quite a lot of problems lately where some of my users have been hammering my server with hundreds of requests per second. Its really irritating to have to blackhole them everynow and then. If BIND can't do this, is there any better solution? Appreciate all the help. Thanks.
