Public DNS Server List By Country

Well, currently I use Swiss Privacy Foundation's DNS but I am always open to options, so I was searching and found this page. You might take a look:

http://public-dns.tk/

This is the biggest list I have ever found online and they are checked continuously! Also you can download the list as json/txt/csv/xml.

If you could test in GRC's DNS Spoof test it would be nice.
Feedbacks?

 

Just checked the german list... I'm curious to see the ping responses

 

A useful insight for the DNS root zone[1] and the thirteen clusters[2]:

The function of DNS is mapping an IP address to a human readable URL: every DNS server must connect to root servers to translate an URL to IP.
The root servers are 13 clusters and one of them is: G.ROOT-SERVERS.NET with IP Address 192.112.36.4 and the Operator is:
U.S. DOD Network Information Center

How can I know when my DNS service uses this specific G.ROOT-SERVERS Cluster? If you deactivate firewall rules for DNS you may find the specific cluster IP on the log, look at denied connections on port 53... So, should I block the specific cluster IP on UDP port 53 connections?
