  1. Securolytics, has some new high-speed public DNS resolvers for use by the Internet security community. (resolver1.securolytics.net) (resolver2.securolytics.net)

  2. Can someone/anyone please answer? I was using OpenDNS for years but it stopped working, internet connection kept quitting. So I changed to Level3 DNS and it seems to be working great, no more problems, faster than before. I put all these numbers in my DNS preferences though and wonder if there’s any advantage, or any harm, or what:

    • Level3 is pretty solid. The more entries the better, but 7 may be overkill. If you are going to use multiple DNS servers, I recommend using (2) from Level3 and then (2) from a different provider. I like Securolytics.

  3. “Depending upon distance between your place and DNS server, there will be speed improvements” this is totally inappropriate!
