bind9 track IP's of clients

Is there a way to easily do this? I know named.stats which can provide insight in to the request / response types and such but I want to see if there is an easy way to monitor # of requests / client

I know you can probably use something like splunk or graylog to plot this data but I am wondering if there is something that is built in to BIND like you can do with stats tracking with 'rndc stats' to get data

Thanks!
