You have recently encountered some difficulties in successfully accessing one or more Internet sites. Your friend who is more experienced in computer science then suggested that you try to solve it by replacing the DNS servers currently in use with more performing ones and you took the indication received as good. However, if you are here now and are reading this tutorial it is evident that you do not have very clear ideas about How configure DNS. If this is indeed the case and if you need some useful advice, know that this time too you can count on me.
With today's guide I will in fact show you how to configure DNS on all your devices, which is the modem, the computer, the smartphone or of the tablet it makes no difference, and, consequently, how to deal with any problems of surfing the net in a simple and at the same time fast way.
So if you are interested in understanding how to configure DNS, I suggest you take a few minutes of free time, sit comfortably and concentrate on reading the information I am about to give you. I am sure that in the end you will be able to say satisfied and that you will also be ready to say that setting up DNS was actually a real breeze. Shall we bet?
Before explaining how to configure DNS, however, I want you to understand, at least briefly, what we are talking about. DNS servers are nothing more than those "translators" that allow you to connect to Internet sites by typing simple text addresses (for example www.google.com) instead of numeric addresses that are very difficult to remember (for example 126.96.36.199) which would then be the real coordinates of the Internet sites. Using fast DNS servers therefore makes it faster to connect to Internet sites than when using slow DNS servers.
On the market there are several DNS servers that can be more or less suitable and performing based on various factors. Personally I suggest you to use the Google DNS server, those of CloudFlare or those of OpenDNS. Alternatively, you can try to find out which DNS servers are best suited to your case by using one of the special software that I have reported to you in my DNS program guide.
The DNS servers of Google and Cloudflare are known and widely appreciated especially for their speed and for the fact that, being international, they also allow access to sites that are blocked by Italian providers. Furthermore, those from Cloudflare promise a high level of privacy (they would not store the data of the sites visited). Even those of OpenDNS are quite fast, they also allow access to blocked sites in Italy, but are exploited primarily for their parental control function through which it is possible to inhibit the display of certain categories of sites: social networks, adult-only sites, gaming sites, Web Mail services and much more.
As I have already mentioned to you, then keep in mind that based on your preferences and needs you can configure DNS both directly on the modem and on the device itself, for example on a computer, smartphone or tablet. In all cases the final result is practically the same, the choice of which solution to adopt is therefore up to you alone.
Configure DNS on Modem
Do you want to configure DNS by acting directly on the modem in such a way as to avoid making changes to the settings of each device in your possession? Well, that sounds like a great idea! To configure DNS on modem proceed as follows. Open your favorite web browser and connect to the address 192.168.0.1 oppure all'indirizzo 192.168.1.1 to access the device management panel. If you can't access the modem management panel with neither of these two coordinates you can try to consult my tutorial on how to find router IP address to find out how to find the correct address of the device.
Please note: On modems supplied directly by telephone operators it is not always possible to configure DNS since all the parameters necessary for surfing the net have already been made available automatically by the provider.
Then fill in the login form that is shown on the screen by typing your username and password to access the device settings. If you haven't changed them, usually the combinations to use to login to the modem settings are admin / admin or admin / password. In case of problems or if you want to get more information about it you can consult my tutorial on how to find out the modem password.
Now that you have logged into the modem management panel, go to the connection status section and try to locate the items DNS 1 o Primary DNS e DNS 2 o Secondary DNS. The numerical digits present in correspondence with these indications are none other than the addresses of the DNS servers currently used by your Internet connection.
Then check the box corresponding to the item Use questi server DNS or in any case the one indicating your desire to configure DNS, fill in the fields relating to the two DNS servers with customized addresses and then click on the button Apply, OK o Save in order to confirm and apply the changes. Keep in mind that after configuring DNS on the modem it may restart, if so do not worry, everything is normal.

If you use a smartphone or tablet Android and you want to understand how to configure DNS, know that to do this you will first need to assign a static IP address to the device when you are connected to a wireless network. To do this, access the device screen where all the apps are grouped, presses on Settings, select the voice Wi-Fi and keep your finger pressed for a few seconds on the name of the wireless connection you are connected to.

Keep in mind that the procedure for configuring DNS on Android smartphones and tablets that I have just indicated is valid only and exclusively in the case of connections made via a wireless network. If you are interested in configuring DNS even if you are using a data connection, know that you can contact Cloudflare's application 188.8.131.52, which allows you to install a VPN profile through which to convey requests for address resolution to Cloudflare's DNS servers. , even under the data network.
To use the app in question, install it via the Play Store, launch it, skip the presentation screens and press on first Install VPN Profile and then OK for two consecutive times. Then move up ON the lever to activate Cloudflare's DNS use and add the application to the list of “protected apps” to prevent it from being disabled when the phone screen turns off. To do this, you need to go to the menu Settings> Advanced Settings> Protected Apps of Android and move on ON the lever relating to the application 184.108.40.206 (be aware that the steps to be taken may vary slightly depending on the device and the version of Android in use).

The above procedure applies only to Wi-Fi connections. To also change the DNS used for the 3G / 4G network, you need to install the Cloudflare app 220.127.116.11, which installs a VPN profile through which all address "translation" requests are sent to the DNS servers of this well-known service (which then prevents the use of other VPN services).
