They do this via DNS anycast routing, by returning the closest server’s address when you perform a DNS query via your DNS server.0Every request sent through a DNS server can be logged and that data collated.

Udp is connectionless protocol, so it means if you have lots of hop’s (networks) to travel to google dns you will lose packet or two. Lost packets in your case mean delay so I would stick to closest DNS you can find to get faster response.0Use your ISP’s DNS servers they are closer to you, and they are less likely to be monitoring your traffic than google is.0For most ISPs, it’s a no brainer because their DNS tends to really suck. DNS makes a huge impact for user experience.

The only way to really decide is to benchmark it. It is going to be different depending on your connection. You should use a tool like to find out what is really quicker.0I simply PING’ed the ISP / Google DNS servers IP, and the results favored the ISP, before and after altering the DNS Primary and Secondary configuration. 26ms vs 77ms.0
