Well, at first glance it looks like malicious activity, so the best action is to call all users, suspected in sending such requests, and warn them. The fast and very (very-very-very) dirty solution is to set up zone 84822258.com <http://niqcs.www.84822258.com> on your resolver. This should supress outgoing queries and thus minimize resolving time.
