There are a plethora of DNS Servers available, but you should consider changing it to the closest or rather the fastest DNS server to ensure high-speed internet connection. Performing a DNS speed test is easy, thanks to the folks over at CleanBrowsing who have developed this simple script to do it.
Steps for Performing DNS Speed Test
- Start by opening Command Prompt (on Windows) or Terminal (on macOS/Ubuntu).
- Then clone the script created by CleanBrowsing developers by entering the following command in the terminal/command prompt.
git clone --depth=1 https://github.com/cleanbrowsing/dnsperftest/
- Now change the directory to dnsperftest by entering the following command.
- Finally, perform the test by entering the following command. This command will auto-sort the list based on the ping (lower on top). This action might take up to 20 seconds.
bash ./dnstest.sh |sort -k 22 -n
Go ahead and set the fastest address on your WiFi router. In this way, you’ll not have to set it manually on each of your devices.
