Your local Internet Service Provider (ISP)might not have the fastest DNS servers that slows down your browsing speed. Often we find ourselves stuck into pages like Facebook are not loading or similar issues. So it’s time to change your DNS to the best possible DNS available in the market i.e. Google Public DNS.

 Google Public DNS.

When people ask us to help them with their DNS configuration, we often point them to different DNS Lookup Tools. But there is something that we can do at our own also with just a little manual work, we will discuss it later.


The Domain Name System (DNS) protocol is an important part of the web’s infrastructure. It serves like internet’s phonebook. Whenever we search for any website our computer performs a DNS lookup. In complex websites our computer has to do multiple lookups. That’s DNS of your connection has to be good so that it can perform fast.


  • IT IS VERY FAST                                                 

Google has their own public DNS service available on a global anycast network that provides all of the advantages of anycast for the queries made to them. An anycast network provides speed boost to your computer allows you to browse very fast.


One of the bigger problem is that local public DNS servers can be used in Denial of Service and Amplification attacks by making a small query which returns a large response. Google has taken care of the common attacks.


Why we suggest customer to switch Google Public DNS because their network is set to improperly configured resolver. One of the key features of Google Public DNS is it provides correct result every time you search for something.


Before you Start be sure to write down the current sever address on a paper. It’s important to keep those number backup, in case you need to revert anytime.

  • 8.8.8
  • 8.4.4

Google Public DNS IPv6 addresses are

  • 2001:4860:4860::8888
  • 2001:4860:4860::8844
