DNS lookup time measurements generated by namebench are stored in /tmp/namebench_*.csv, so you can do any custom analysis if you want. To compare DNS servers, namebench performs DNS lookup on hostnames found in your web browser history, or Alexa top 10,000 domain names. It does an analysis and later shows us the results to see if the DNS we are using are correct or we could improve the speed.

We can use it for free on operating systems such as Windows, Linux and macOS.

Sample DNS Speed Test Results by namebench DNS Speed Comparison Summary: Mean/Minimum DNS Response Time: DNS Response Time Distribution: Namebench is a free program that aims to show which are the best DNS that we can use to test our connection and to tell us which are the fastest DNS servers that we can use. A typical DNS benchmarking report generated by namebench looks like the following. When run in GUI mode, namebench will show DNS speed test result in a web browser window. Saving detailed results to /tmp/namebench_2337.csv Saving report to /tmp/namebench_2337.html Recommended configuration (fastest + nearest): When run in command-line mode, namebench will, upon completion, prints out benchmarking summary (e.g., recommended DNS configuration) in the terminal as follows. namebench will test your local DNS servers, as well as public and regional DNS servers. Click on Start Benchmark button to start DNS benchmarking. If you running namebench in a Linux desktop environment, namebench will launch a graphical interface as follows. If you don't have X11 installed, namebench will automatically proceed in command-line mode, and start evaluating available DNS servers right away. To install and launch namebench on CentOS, RHEL or Fedora: $ sudo yum install tkinter

#Google namebench dns how to#
In this post, I will describe how to test and compare DNS server speed by using namebench. using a free utility called NameBench developed by Google to automatically test the performance of all of the popular DNS providers for your location. namebench can run in command-line mode as well as in GUI mode. On Linux, there is an open-source DNS benchmark tool called namebench which can help you find the best DNS servers to use. Before switching to different DNS servers, you probably want to compare DNS server speed among available DNS servers, and find the best DNS for you. If you are not satisfied with the default DNS service, you can consider using other public DNS services such as Google DNS, OpenDNS, etc. Without manual configuration, your Linux will be set to use the DNS service offered by your ISP or organization.
