More info on Google Public DNS: https://developers.google.com/speed/public-dns/
In this video I give a tutorial on how to speed up your internet to make it faster and fix problems by switching to Google DNS. In the video I show you how to do this with Windows as well as Mac OS X and a Belkin router although you can do this with any internet router or modem. Google DNS is generally going to be faster at resolving DNS queries which can sometimes make web pages load a second or more faster and is also very helpful if your internet only works intermittently.
