It was straightforward to count these queries by client address.

Of the 422,061 queries with the reverse domain flag (-d/--reverse-domain):

* There were 1,460 client IP's in total.
* 314,239 (74%) of queries didn't return anything (no matching object, or malformed query such as "in-addr.arpa" or "ip6.arpa").
* 3 clients accounted for 44% of the queries that did return at least one object.

Of the 758,583 queries for domain objects by primary key (*.in-addr.arpa|ip6.arpa|e164.arpa):

* There were 26,073 client IP's in total.
* 501,457 (66%) queries didn't return anything.
* 4 clients accounted for 65% of the queries that did return at least one object.
