Video-post in which I explain step by step and without having to download any third-party application, the way to change Android DNS to Cloudfare DNS which are the ones that are in fashion right now since everyone is talking about them.
Well, actually I'm going to explain it to you, How to change Android DNS to Cloudfare DNS or whatever you want from the many there are to choose from.
In the video that I have left you at the beginning of this post, you will find the process of changing the Android DNS for Cloudfare or those that interest you the most. Next I will comment on what DNS is with a totally colloquial language so that everyone understands it, as well as what happened to leave a list of the best DNS of this year 2020, DNS that you will be able to use as you wish to test which is the one that best suits your personal needs.
What are DNS?

DNS stands for DOMain Nsoul System and what it does is translate domain names, or what amounts to the same thing, the web addresses that we all know and have in mind, such as Androidsis.com, in its corresponding IP address, which is actually how web pages are saved.
This process that today I teach you to do step by step in the attached video that I have left you at the beginning, It is also a process that can be done by entering the Router's configuration and changing the DNS that come by default from our company for other different DNS that offer us greater security or to be able to access sites that our company has banned in its DNS.
The difference we find When doing it directly in the Router, the changes once the Router has been restarted will serve us for any device that connects to that same Router either via Wifi or via Ethernet cable.
By doing it directly on our Android devices, we are going to be able to do it in a faster and easier way but we are only going to apply those new DNS to the terminal in question. This must be taken into account, even though we can change the DNS to any device that we have connected regardless of the operating system that is used, whether it is a personal computer PC or MAC or Linux Tablet Android or iOS, etc. etc. (The only thing is that the DNS change process is obviously different in each of these operating systems).
Main DNS or best DNS of the moment (All public and free)

- CloudFlare: These are the DNS that have become fashionable and that everyone is raving about, the DNS to use would be the following according to our personal interests: 1.1.1.2 and 1.0.0.2, Only Anti malware. 1.1.1.3 and 1.0.0.3, Anti-malware and avoid adult content.
- those of Google which are the ones that come by default in all Android: 8.8.8.8 and 8.8.4.4
- Comodo Secure DNS: 8.26.56.26 and 8.20.247.20
- Open DNS Home: 208.67.222.222 and 208.67.220.220
- Norton ConnectSafe: This DNS server has three different options depending on what we are looking for: Option A: 199.85.126.10 and 199.85.127.10 Protection against malware, phishing and fraudulent sites. Option B: 199.85.126.20 and 199.85.127.20 Protection against pornography. Option C: 199.85.126.30 and 199.85.127.30 Pornography + others (gambling, suicide, drugs, alcohol ...).
As I show you in the video that I have left you at the top of this article, do not be afraid to experiment and test which of these DNS best suits your specific needs, higher speed, greater privacy, better connection stability, etc etc.
Right now we recommend those from Cloudfare since they are the best in public DNS servers to prevent malware and adult content.
