I've continued to update my dataset originally posted about two weeks ago.  Please take a moment and review your CIDRs 
which may be running an open resolver.

I've exposed one additional bit in the user-interface that may be helpful.  Some DNS servers will respond with RCODE=0 
(OK) but not provide recursion.  nearly 90% of the servers in the database provide recursion.
What is the rationale behind listing servers not providing recursion on a list of open resolvers?

As far as I know, responding either NOERROR or REFUSED produces packets of the same size.
