Free and Free Mobile Internet failure: DNS is in question, how to change it?

Although it is often blame bad luckThere is nothing more frustrating than the internet shutting down. And that’s the price Free and Free Mobile customers paid a few days ago. However, failures do occur quite regularly (last affected TV) but most of the time, the problem can be fixed with a simple DNS change, these addresses (to simplify) translate what you type in the address bar. IP addresses. Without DNS servers, it is not possible to connect to websites via web addresses!

First of all, try typing the IP addresses of the 5 most visited sites in France directly into the address bar to see if you can fix the problem with a simple DNS change:

  • Google FR :
  • :
  • :
  • : or or
  • : or

If you manage to connect to these sites this way, you will need to change your DNS to regain your normal internet connection during the outage. Using other DNS other than those provided by your ISP is usually OK, you can leave the configuration as is.

Panne Free: How to choose the right DNS, top 5 server list

There are many third-party DNS address providers. One of the best known is undoubtedly Google because of their very easy-to-remember addresses. But there are also many free alternatives we recommend: A malicious DNS provider can indeed easily redirect you to scam sites and/or spy on what you are doing. Another selection criterion is the delay time. The speed with which a particular DNS server translates domain names to IP addresses depends on how far away you are.

So for some people Google’s DNS will be faster than others where it would be wiser to choose OpenDNS addresses. There are of course benchmarking tools to know the latency of DNS addresses, but we won’t cover them in this tutorial. Here is the list of top 5 DNS services at the time of this writing:

  • quad9 :
  • OpenDNS :,
  • level 3 :,
  • FDN :,, 2001:910:800::12, 2001:910:800::40
  • Google :,

You’ve noticed that DNS usually comes as a pair of addresses. The first is the address favoritesecond address alternativewill be used only if the first one is unavailable. Few people take advantage of the fact that you can mix these addresses: Quad9 for example favoriteand on Google alternative. However, it is recommended especially if you want to both reduce your reliance on a single service as much as possible and reduce your chances of finding yourself online in the future due to a DNS issue. .
