Hi, guys! After a little research, I’ve discovered that third party DNSs are much better than what ISP gives you. Therefore I’ve decided to switch, but to which one? The Google’s DNS or Cisco’s newly acquired Open DNS? Which do you use? 
Norton DNS >> https://connectsafe.norton.com
Open DNS.

My memory of Open DNS (before getting fast fibre optic broadband) was its configurable settings - allowing family friendly settings - allowing more that just being a DNS service.
Dont know, just guessing … Since Norton work with all types og security stuff 24/7 they may be better at blocking malicious URLs
