Thank you for that very detailed information! Very well explained and clear to the point slides. I have one question: what do you mean when you say "instances"? For example "over 750 instances"? Thank you in advance!

I have been confused about this question for a long time. Is the resolver the ISP or the getaddrinfo() function executed in our local machine? Or Is it depended on what type of query you run, iterative or recursive?
