Google recently introduced Google Public DNS service. Last week, I wrote about what Google Public DNS actually means to you. If you are not aware of what it is I recommend reading that post before reading this further.
With a couple of different options with DNS Servers now between your ISP’s default DNS server, the time tested OpenDNS project and the new Google Public DNS server, you might be wondering which one of these should you be using.
Namebench is a free tool that’s here to answer just that question for you.
It runs a bunch of tests and finds the fastest DNS server available for you. It runs a pretty exhaustive bechmarking by using your web browser history, tcpdump output or even standardized datasets to give a personalized recommendation.
Namebench is a free download and works on Windows, Linux or Mac OS X. It sports both a GUI (graphical user interface) and a command line interface.
It does not install anything in your computer but just runs standalone. Here is a sample Namebench result after a run.
You can choose to use this DNS settings and you may be able to realize faster browsing speed.
