Why are all of the top performing servers listed as unknown name, unknown owner?

Why are a large portion of the top performing servers listed as unknown name, unknown owner?
These IPs have hostnames, and a simple whois shows the IP owner.

1.0.0.1 resolves to 'one.one.one.one'
208.67.220.220 resolves to 'dns.sse.cisco.com'
etc.

I don't know how dnsbench is coded, but it should probably resolve IPs and owners outside of the local machine's DNS configuration,
I use technitium DNS server on my local workstation, which I have configured to listen on 127.0.0.1.

I don't know if that is the issue, but based on the following text, maybe dnsbenchmark does not understand my configuration.

NOte: The wierd thing is some of the host names do resolve for the less optimal servers.

I'm going to guess that @Steve would say you are in an unsupported configuration. (Or maybe there's an off chance he might address it, but it's certainly not the sort of situation the software is meant to address.)

My guess is that you should disable this technitium software for your testing, to get your best result from the actual upstream servers, and then use that info to configure your local DNS software.
