DNS is the acronym in English for Domain Name System which is responsible for directing the traffic of the entire Internet. We show you how to navigate faster just by modifying this parameter.
The DNS is responsible for translating the domain names of the pages that you enter in your searches from the browser, such as Computerhoy.com or HobbyConsolas.com, and returns them to the browser translated in the form of the IP of the server on which they host the web, something like 23.256.23.76 or 84.89.210.23.
Therefore, we could say that a DNS server is the "translator" between the searches that people do and the hosting data that the devices need to reach the web pages that you request.
The faster and more efficient the translation service is, the faster you will get to the page. In other words, in general, the faster your browsing will be.
In addition, DNS servers can also be used to restrict traffic to certain websites, so DNS can be a censorship tool in some countries. Just by changing the DNS server that your computer uses, you can bypass these restrictions to, in addition to improving connection speed, improve privacy.
OpenDNS
OpenDNS is one of the biggest names when it comes to free, public DNS servers. It has been in business since 2005 and is now owned by Cisco.

Privacy is another important point when using Cloudflare, the company will not use your browsing data to publish ads but will delete any record of your browsing in the next 24 hours.

Google Public DNS
Google extends its tentacles to almost every corner of the web sphere, which is why Google Public DNS servers are no exception. In addition, it is a free service that provides a simple and effective DNS alternative.
