Hrm, interesting idea. But the answer is: no, there isn't a way. The
simplest way to implement something like this would be to add a new
aggregating function. So one could do something like:
To get /24 and /64, respectively.
I'll throw this idea on the ever growing pile of things that can be worked
on :) Obviously, I can't make any promisses about this ever getting done.

Aggregating based on a subnet definitely makes sense.

I haven't played with these events, but at least based on the docs ,
auth_client_userdb_lookup_finished and auth_client_passdb_lookup_finished
events seem to have the remote_ip field as well as an error string on
failure. Does that give you the info you need?
