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. Sample DNS Speed Test Results by namebench DNS Speed Comparison Summary: Mean/Minimum DNS Response Time: DNS Response Time Distribution: 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. Try tool with Google NS 8.8.8.8 or read namebench FAQ. This page shows the performance results of each DNS server in both graphic. Namebench results suggest unilu DNS server is doing very bad things to our network Google,Paypal. namebench will test your local DNS servers, as well as public and regional DNS servers. namebench latest version: Enjoy a faster.
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 To install and launch namebench on Debian, Ubuntu or Linux Mint: $ sudo apt-get install python-tk
In this post, I will describe how to test and compare DNS server speed by using namebench.
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. This is a free project that is in continuing development, so results might not be perfect, and there may be more features added in the future. Without manual configuration, your Linux will be set to use the DNS service offered by your ISP or organization.
