    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?

    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?
