We previously posted about why you should use external DNS Servers, and how it increases the browsing speed of your internet connection, then we had also posted about how can you change the DNS servers with the utilities like Google DNS Helper and DNS Jumper
Today we will tell you about another free to use tool called NameBench which will let you know about the fastest DNS servers you should use to maximize internet speed. It runs a fair and thorough benchmark using your web browser history, tcpdump output, or standardized datasets in order to provide an individualized recommendation. It is completely free and does not modify your system in any way.
This small and easy to use tool runs on Mac OS X, Windows, and UNIX, and is available with a graphical user interface as well as a command-line interface.
