There is so much I do not know about dns. I thought: I ask dns server about domain, they return an IP address. I connect to IP address and they in turn can see mine. So why does cloud flare need to a) query domain for IP address on my behalf? Can’t they just do it on their own behalf and cache the results? B) why do they need to hide my IP address information from the domain? Aren’t I going to visit the destination regardless?
