I’ll take a stab at this well from a different angle. (Oh…that’s called a “hocho” knife)
The OP mentions Latency. Correct me if I’m wrong, but 184.108.40.206 is a caching name server, just like how Cloudflare POPs are caching servers for websites. Use the 220.127.116.11 nearest you for best performance. Not that you can change which 18.104.22.168 server, but the default server you get is the best choice.
Thanks for the replies. It is good to know that all servers in the infrastructure are managed by Cloudflare.
However, there is weird stuff going on around here, that is beyond my and your control. It would be great if the DNS queries can go through a server located in a different country. Some increase in latency is fine.
