I need to point out that Norton DNS has been retired and is not supported anymore (and never offered any privacy).

"On November 15, 2018, Norton ConnectSafe service is being retired or discontinued meaning the service will no longer be available or supported. You may continue to use ConnectSafe until November 15, 2018. However, we do recommend that you take a moment to review important details related to this announcement below."

Some alternatives: https://medium.com/@nykolas.z/norton-connectsafe-dns-is-shut...

I am actually surprised he didn't mention CleanBrowsing in their list, which I would recommend as good alternative to Norton and OpenDNS.
