I’m not sure what data you want to get out of that research, but IMHO it is upfront missing a definition of what a resolution error is. One could infer from the survey that you mean anything that does not have the result code NOERROR, but don’t think that is a good measurement as: - NOERROR/NODATA could also be an resolution error for the the end user. - NXDOMAIN and other result codes are normal part of operating DNS and normally nothing to worry about. I just logged in to a random server that is doing tens of thousands of requests per second and it had 15% NXDomain queries 1% SERVFAIL and REFUSED and 0.1% FORMERR and that is a typical RCODE distribution, and it would be impossible to follow and investigate all of them.
