Guide to Change DNS to Google DNS:To change your DNS to Google DNS or Open DNS all you need to do is edit your network settings which is very easy in windows. Find your active Internet connection. Either from notification area or from My Computer > My network places > Network connections.
Click on Properties > Internet Protocol >TCP/IP and change your settings in “use the Following DNS server ”
That’s it and within second you will be able to start using Google DNS. I find this useful at many places, when your default DNS fails to load any web page and this usually happens with BSNL and MTNL DNS. Also, if you are changing name server of your site, Google or open DNS, replicate the changes faster and you will be able to access site with new settings.
Well, this quick tutorial will help you to get started with new DNS settings instantly. But, in case if you are stuck anywhere, feel free to let me know via comments.
