What I would like to do is point QDNS at some other DNS servers

The only reason you should get different answers from different DNS servers is because of timeouts, and they should be very rare. Any other discrepancies between different DNS servers would indicate a serious misconfiguration somewhere.
("Split Horizon" DNS configurations can be used to give different DNS results for an Intranet than on the Internet, but that shouldn't be a factor in this case).
75% resolution is really pretty good. There are many IP addresses that do not provide resolved names and it's typical to see as much as 40% unresolved.
If you want to get more useful information out of the IP addresses, you could try jdresolve which composites fake "names" from the IP address and the domain of the controling entity that owns the IP block the name is in. This may give you better results in you analog domain and organization reports although the valifity of these may be suspect.
