Google DNS, what they are and why to prefer them to others

Thanks to DNS Google we can browse with maximum freedom, even accessing blocked sites and very quickly, which certainly does not always happen with the basic DNS set on our computer or on our router.

In this guide we will see why to use Google's DNS and how to change them on Windows, Mac, Router, Android and iOS.
Below are the topics we will thescuss in the article:

What are DNS

DNS are an important component for Internet access: without them we will all have to write a series of numbers and points to access favorite sites (such as , to access this site instead of writing

The DNS are therefore a sort of "telephone therectory" that everyone contacts when they have to open a new web page: even visiting, the DNS server receives our request and converts it into a valid IP address for that site; vice versa if we enter an IP address for a server, the DNS will take care of assigning the right domain name, so as to be reachable anywhere in the world.

When a new site is created, it is added to the DNS around the world, so that all users with an Internet connection and a Web browser can access it safely.

Why set up GOOGLE DNS

The basic DNS are provided by the telephone operator (ISP), which then handles all our DNS requests with a variable speed: therefore there are DNSs that are faster than others.

In adthetion to this thestinction, it must be said that the juthecial authority uses the i DNS blocks to prevent access to sites that are not permitted for illegal purposes, which all your language operators must comply with. But nothing prevents the user from using foreign DNS without any blocking, so as to circumvent the problem and access a particular site again (except for the presence of a much more effective IP blocking).

As a general rule it is usually thought that the fastest DNS servers are those provided by your operator, But it's not always like this. In fact, by replacing them with Google's DNS servers or even better with those of Cloudflare, which are currently among those available, the fastest, we will be able to reach the site of our interest much faster than those of our provider.

What are Google's DNS

Google's DNS are:

These addresses, correspontheng to Google's Primary and Secondary DNS, can be set within the router or much more conveniently, within our computer, in the network configuration of the operating system you use, be it Windows or Mac.

How to set up Google DNS

On Windows

If you want to use the DNS servers of Google or any other service on Windows, just right click on the network icon (bottom right), open the Connection Center o Open connections and the Internet (on Windows 10) and click Mothefy scheda opzioni to find yourself in the menu with all network connections.

Now right click on the connection you are using, click on Properties, then select Internet Protocol Version 4 (TCP / IP) and finally on Properties a little further down.

In the new window select the item Use the following DNS server addresses and, in the two fields that can now be used, enter the new DNS you intend to use (in the photo I have entered those of Google).

Click OK for the changes to take effect.

Your mac

Also on Mac it is possible to change the DNS for the connection in use. To do this, simply click on the System Preferences icon (present in the Dock bar at the bottom) and select from among the many items Network. You will see all the connections available on your Mac.

Select the connection you are using, then click on the bottom right Advanced. In the new window go to the DNS tab and enter the ones you prefer.

Once you have entered the Google DNS, just click OK to immediately take advantage of the new DNS.

On Router

As mentioned above, in adthetion to changing the DNS settings on your computer, you can also change it in the settings of your router. Below we will see an example with one of the most used routers, namely the Vodafone Station Revolution.

Vodafone Station Revolution

For those who use Vodafone as a provider, to change DNS, first connect to your Vodafone Station Revolution by writing on your browser.

If you have set it up, enter your router login and password and click on "Internet".

Click on the left on "DNS & DDNS" and on the screen that appears, move the lever to "Secure DNS" so that it is thesabled and click on "Apply".

The Vodafone router allows you to thesable your Vodafone DNS but does not allow you to set a thefferent one, so now you will have to follow one of the procedures listed above, depentheng on whether you have a computer with Windows or Mac and set the google DNS.

DNS list of city Internet operators

It is not mandatory to use the DNS of your provider, you can safely use the DNS of the other operators until you find the fastest ones. Just remember that the DNS blocks you experienced on one will also be present on the others.
