After saerching the web for a tool for Ubuntu to test DNS servers, I have found Namebench. This tool allows via a graphical user interface to perform tests that will help you decide which DNS servers work best and fast for our Internet connection.

Namebench is a cross-platform application that can be run under Mac OS X, Windows and GNU/Linux. In this tutorial, we will show you how to install Namebench on Ubuntu.

1. Install first this dependency to be able to use a GUI for Namebench:

sudo apt-get install python-tk

2. Using the Terminal, run these commands to install Namebench (v1.3.1) on Ubuntu:

wget http://namebench.googlecode.com/files/namebench-1.3.1-source.tgz
tar -zxvf namebench-1.3.1-source.tgz

Then start it with this command:

4. In the window that pops up, submit name servers separated by a comma, then click Start Benchmark to start your test.

Wait for a few minutes until the test is finished in order to view results. The result page will open in Firefox:
