Speed ​​up Internet browsing by changing DNS servers

0 146

Does your Internet browser seem a bit slow? Change the DNS servers on your PC! By using alternative servers, you should gain speed.


The Domain Name System - DNS, or domain name system, in French - is an IT service used to translate Internet domain names into IP addresses. It is actually a directory that matches the name of a website - more precisely, its URL like www.nomdesite.com - and its IP address - a group of numbers that specifies its physical position on Internet. A bit like a phone book that links the name of a subscriber to his phone number.

Fast and free DNS servers

However, if the DNS is a universal system, it is neither unique nor centralized since it relies on numerous servers acting as directories. Internet service providers therefore have their own DNS servers. By default, these are the servers that your browser uses whenever you visit sites. But they are not the best, nor the fastest.

Fortunately, whatever your browser, operating system or Internet service provider, you are free to choose the DNS servers you use! You can perfectly use alternative, free and much better DNS, by modifying the associated parameters on your computer - in fact the IP addresses of the servers. Not only will this speed up your Internet browsing, but in addition, changing DNS servers can allow you to access websites that your Internet service provider has blocked for various reasons!

In what follows, we show how to change the DNS servers in Windows 10, but the procedure is similar for previous versions of Windows.

Choose alternative DNS servers

First of all, you should choose the alternative servers that you want to use instead of the DNS servers of your Internet service provider. Here is a selection of the most popular free and fast DNS servers, with IPv4 and IPv6 IP addresses, the two current versions of the IP protocol, of the two DNS servers (main and auxiliary).

IPv4: 8.8.8.8 et 8.8.4.4

IPv6: 2001: 4860: 4860 :: 8888 et 2001: 4860: 4860 :: 8844

IPv4: 1.1.1.1 et 1.0.0.1

IPv6: 2606: 4700: 4700 :: 1111 et 2606: 4700: 4700 :: 1001

IPv4: 208.67.222.222 et 208.67.220.220

IPv6: 2620: 119: 35 :: 35 et 2620: 119: 53 :: 53

Once you have made your choice, all you have to do is write down the corresponding IP addresses (or copy and paste them).

Access DNS changes in Windows 10

  • Go down to the bottom of the window, then click Network and Sharing Center.

  • In the left menu of the Network and Sharing Center, click on Change card settings.

  • Right click on Internet connection that you are using and then click Properties in the context menu.

It is from this window that you will be able to configure your new DNS servers.

Configure new DNS servers

To finalize the change of your DNS, you just have to follow the same procedure for the Internet Protocol version 6 :

Here, you can now launch your web browser and take advantage of your new DNS servers, to surf faster or to avoid DNS blocking of your access provider.

Note that to go back, just click on the option Obtain DNS server addresses automatically about Properties IPv4 and IPv6 protocols.
