How to Change Your DNS to Public DNS and Why

Today, I read about an article on Digital Life on how changing the DNS of your computer will speed up the loading speed in your browser. I thought I would like to share it here. If you know something about IP addresses, you would know that we would normally set it to  “obtain an IP automatically”. By setting it to auto, it means that it will perform a DNS lookup to correctly to the website.

Actually, there is nothing wrong with it. However, complex websites  might need multiple DNS lookup. Because of this,  it may slow down the loading of the website.

So, if you use a Public DNS server, with their infrastructure, you might be able to load the website faster. For this case, I chose Google’s DNS server because it provides a clear explanation on how it can be faster and have more security.

How to Change

  • It is very simple to change. Now, I am using Windows 7 as a demo for this change.
  • Locate the “IP Address Settings”
  • For Windows 7, type in “Network” at the Search Box
  • You will see “Network and Sharing Center”
  • Click on “Network and Sharing Center”
  • On the left, click on “Change Adapter Settings”
  • Depending on which connection you are on (Wireless or LAN), Right Click and select “Properties”.
  • Select “Internet Protocol Version 4 (TCP/IPv4)”
  • Add in the Public DNS address to the DNS as shown below

That is it. You are done.  You will now be using Google Public DNS to lookup addresses. Try it and let me know if it speeds up your browsing experiences.
