Internet service providers offer their own DNS servers, which convert domain names into IP addresses capable of being interpreted by machines. Google DNS, OpenDNS, Cloudflare, here's how to choose the best DNS server to surf faster.

The domain names in letters are used in order to be better assimilated by humans. The DNS servers (Domain Name System) or Domain Name System are used to translate character strings into IP addresses which are the real identifiers of each website on the web.



DNS doesn't really have an impact on bandwidth. The latter depends only on the quality of service of the ISPs and other factors specific to each user. However, a close and fast DNS has a definite impact on the time it takes to transmit and receive requests, and therefore on the fluidity of navigation.

How to choose the right DNS?

To choose a fast DNS server, we recommend that you use a test tool to identify the address that best suits your connection. The quality of the servers is not the only criterion that comes into play. The speed of DNS also depends on your geographical position. The most efficient DNS are however effective regardless of the location of the Internet user.

No need to disperse. You can choose to stay on your ISP's servers, use the Google DNS, those from OpenDNS or the servers of CloudFlare which the company touts as the fastest in the world. But there are also other quality suppliers. If you are in doubt, you might as well check the performance of each DNS by using DNS Benchmark tool.


Start by downloading it from the publisher's website. This utility is directly executable and can be used without installation. You have 4 tabs at the top of the interface. Position yourself on the second (Nameservers) to perform the tests.


The developer makes it easy for users. A list of the most popular DNS is already available in the tool (Google, OpenDNS, etc.). It is possible to add other servers manually by clicking on Add / Remove at the top left. Then click on the Run Benchmark button on the right.

Wait for the test to go to the end and check that the box Sort Fastest First is checked in order to sort the results by displaying the fastest DNS first (those with the shorter red bar). A green circle next to the server indicates that it is functional. The status tab allows you to consult in more detail the status of each DNS server.

Depending on the results of the servers tested, you can adopt the ones that you think are the fastest for a smoother surfing experience. And don't forget that only daily use can give you a clear opinion. So do not hesitate to test several DNS servers in order to choose the one that suits best after an initial filtering with DNS Benchmark.
