I shall gather that data again for i am not running qtype stats on our
recursives at the moment, but last time i checked it was more like 75%
IN A queries.
I can only assume that MX records are queried more frequently for
otherwise stale domains or DNS usage in general has changed very rapidly
over the last few months. It might also be that our broadband customers
are not all that worm/malware infested like others but that would really
surprise me. ;-)
