Just like OpenDNS and Google Public DNS, Symantec has introduced Norton DNS for Windows and Mac OS X which is currently in Beta stage.
Norton DNS Public Beta offers you a faster, safer, and more reliable Internet experience. To enable and use Norton DNS, simply set your DNS server addresses to 22.214.171.124 and 126.96.36.199. You can visit http://setup.nortondns.com to verify if Norton DNS is working or not.
