Secure DNS servers

I was sure this has been already posted on my blog, but I guess I was wrong (or was it my old blog). Anyway, here they are, listed again. Most widely known and used DNS servers that can be used as alternative to the DNS servers provided by your ISP. In general, most users don’t really need to use these, but those who want extra security in a form of blocking websites that are serving malware or host phishing sites along with DNS poisoning defense, these alternative DNS servers can be useful. Some (like Norton ConnectSafe also offer blocking of porn, but you have to visit their webpage for those IP addresses, I’m only listing the antimalware/antiphishing one). Instructions to use each are also provided on their webpages if you don’t know how to set them up.

  1. Hello Rejzor,

    Thank you for sharing this listπŸ™‚, but do you plan on testing them (including Yandex DNS and ranking them based on best overall blocking of malicious websites (including grayware/whatever like spam, scam, adware, phishing, potentially unwanted software, browser exploits, et cetera)?

    I think that it would be nice to see how you rank them in terms of malicious website protection.πŸ˜‰

    Thank you,

    1. From my experience, Symantec DNS is the most aggressive. The rest doesn’t really block much. Haven’t tried Yandex yet though. I mostly use these for reliability over protection. Antiviruses usually have much better URL blocking anyway…


      1. Hello Rejzor,

        Thank you for responding.πŸ™‚

        You are right about antimalware/antivirus products usually having better URL blocking, but I like to have layers of protection especially layers that do no need to be installed and that can work across different operating systems; and I often use inferior antimalware products like Microsoft Security Essentials/Windows Defender and ClamTK because they are a better fit for the people that I usually help who can not handle having to register their products or buy their products or deal with ads in products et cetera so having extra layers is helpful.

        I use Windows and Ubuntu Linux so having an extra layer of protection for my Ubuntu partition is helpful even though malware has never been a problem on this partition yet but I like to have some protection, most people who I help with computer problems usually have malware infected computers because they do not have functional or updated antimalware products and most of them need automatic layers of protection to help them because they do not know much and are not willing or able to learn, and so every little automatic and free layer of protection like that helps a bit.πŸ˜‰

        I hope that you and/or someone else will do an annual test of these free DNS services to see how they rank in malicious URL blocking each year, it would nice to have updated tests each year from different people to have a better idea of how well they perform, because most of the tests that I have seen are from years ago and I have seen no test for Yandex DNS because it is the newest.

        Thank you,
        -John Jr
