It uses the same
host-statistics-max options, as documented for bind8. Only IPv4
is supported, so all others queries (IPv6) will appear in the count for "0.0.0.0".

However, if you wish to use this on a high traffic server with close to that many clients, you probably want to turn up the HOSTSTAT_HASHSIZE to something larger than 1k to reduce the overhead of walking the linked lists. It could also be made more efficient by storing the entries in order and using a binary search, but I didn't need this, so I didn't code it.
I also didn't care what the responses were, just where queries were coming from, so I only tracked total queries (as "TotalQ"). It would be fairly easy to add support for more counters, as the TotalQ counter is incremented in the same function which implements the other statistics counters.
