You could try running a test with -bh and also turn debugging on with
-d9 and see if any of what you get makes sense.. :-)

Those different lookups could all access the same file. They are just
probing it with different keys. For example, if you receive a call from
192.168.23.45 it would first lookup "192.168.0.0/16", and if that
failed, it would look up "192.0.0.0/8". (In practice, you'd probably
want to put the /8 lookup first.)
