Compare Your ISP DNS Speeds With Google & OpenDNS

[iMav]

Here's a tool I came across that allows you to compare the speeds of your ISP's DNS to that of Google's & OpenDNS'. All you need to do is download a java file, run it in command prompt with your ISP's primary DNS as an argument to the command.

So first download the jar file from here. And then start Command Prompt, navigate to the folder where the jar file is saved and type the following command:

java -jar browsermob-dns-perf.jar 123.456.789.012

NOTE: Replace 123.456.789.012 with the primary DNS of your ISP. The process takes time.

My speed results:

Lower is better.
