First, you need to know 3 things about the DNS:

  1. What's DNS (see here)
  2. What benefits can DNS bring us? (below)
  3. How to change your DNS settings (see the 'Related Links' part below)

Public DNS is a free, global Domain Name System (DNS) resolution service, that you can use as an alternative to your default/current DNS provider from ISP.

Why using  Public DNS

  • Performance - speed up your web browsing experience
  • Accuracy
  • Clean and Safe - improve your network surfing security
  • No Annoying Advertising from ISPs - get the genuine web results without redirect ads contents
In the end, you can pick up one (suitable for you) of the best free public DNS servers (collected from all over the world) below and start using it.
