Change DNS directly on your Freebox, simple, efficient and durable

This is ideal if you have access to your Freebox OS handy. Changing the DNS directly on the box will allow all the equipment connected to it to benefit from the modification (this information is indeed shared with the devices to which the Freebox assigns an IP address in the local network).

  • Go to, enter your password
  • Go to "Freebox settings"
  • Then direction "DHCP"
  • You thus have 5 DNS fields, insert here those you have chosen above.

To apply the changes, your devices must be disconnected and then reconnected to the network in order to request a DHCP lease again.

If you don't want to bother: simply restart. Otherwise a disconnection / reconnection of Wi-Fi or Ethernet will do the trick.

Change DNS in Windows 10: a few clicks are enough

To modify your DNS in Windows 10, the procedure is quite simple. First, go to your search magnifier, usually at the bottom left of the home screen, and type in "Control Panel."

What is DNS (Domain Name System)? 🤔

This "domain name system", as one could translate it into Spanish, makes it easier to find a website in your navigation. It allows you to link a domain name (an address) to a physical IP address. Often, DNS can be compared to a telephone directory, which connects a telephone line to its holder. It's as simple as that.

You must then make a small right click on the connection that you want to modify. Usually, this is your primary Wi-Fi. From then on, click on “Properties” and select the line “Internet Protocol version 4 (TCP / IPv4)” by double-clicking on it or by pressing “Properties” again.

From there, another page opens where you will find, at the bottom, two lines already completed: "Preferred DNS server" and "Auxiliary DNS server". And all you have to do is enter your privileged DNS addresses.
