Your computer seems to have something wrong from the moment you can't access some Internet sites. Talking to a more tech-savvy friend of yours, you were told that to solve this, you could try changing the DNS servers and setting the OpenDNS ones. Unfortunately, however, what concerns information technology is more difficult for you than Arabic and, despite the trust in your friend and his suggestion, you do not have the faintest idea how to carry out this procedure.

What is a DNS
Before we start talking to you about how to set up a DNS, you better clarify this topic for you first, in case you don't have full knowledge.
A website that you visit through your browser is presented in the form of a text string (just for example www.aranzulla.it). This string has some elements, such as the top level domain (in this case.IT) and a second level that identifies the name of the organization you are reaching. The wording may also be present www, in the case in which you are pointing to the server that is providing the Web services. Often, however, when the www is missing it is because you are pointing to a subdomain with respect to the main one.
But behind this string, there is the IP address of the server that hosts the entire website you are visiting. To then reach your favorite websites, you should remember the IP addresses of the servers that host their pages. It is for this reason that a domain is associated with each IP address, such as www.aranzulla.it in my case. In this way the user will only have to remember the web address of the website he wants to visit.
But how does this conversion between web address and IP address take place? It happens thanks to DNS. These are like a large library that contains the real-time correspondence of each web address with its IP address. Each Internet service provider, such as Vodafone, Fastweb, TIM, for example, has its own DNS and, when you type a web address in your browser, this is resolved by your operator's DNS, so that you can reach the IP address of the server. .
In some cases, providers may censor (not by their choice) some Internet sites that are not deemed to comply with current laws. For this reason there are other DNS, such as OpenDNS, which offer a service not bound by any censorship. Moreover, thanks to its community, the OpenDNS service blocks all those sites compromised with malware or pishing, preventing access to them.
How to Set Up OpenDNS on Windows
To configure OpenDNS DNS on Windows, you will first need to reach the Settings Windows, in the section Rete and Internet.
You can reach it by clicking with the right mouse button on thenetwork icon (The white monitor or Wi-Fi cleats, depending on the connection in use) that you can find next to theclock Windows. Then select the item Settings Open connection and Internet.
You can also reach this section by clicking on the button Start (icon with windows flag) found at the bottom left of the screen, and then click on the button Settings (icon with symbol of a gear). After the panel opens Settings, click on the item Rete and Internet.
Now click on the entry State e poi su quella denomtata Change card options, which you find in the center of the screen. A new window will then open showing you all the network devices that allow you to access the Internet.
Now right-click on the icon of the network card you are currently using (be it LAN or Wi-FI) and select the item Property from the context menu
The window will then appear on the screen Property of your network card. From this window, select the item Internet Protocol versione 4 (TCP / IPv4) (but be careful not to remove the check mark) and then click the button Property. You will see that another window has opened and you will now need to locate the section DNS in tab General. Activate the box Use the following DNS server addresses and type those of OpenDNS:
Preferred DNS Server: 18.104.22.168
Alternative DNS server: 22.214.171.124
If you want to use the service instead Familyshield of OpenDNS, which allows you to block adult sites, type these DNS addresses instead:
Preferred DNS Server: 126.96.36.199
Alternative DNS server: 188.8.131.52
Then activate the box Valid impostazioni all'uscita and click sul pulsating Ok in both windows. This way you will have set the OpenDNS DNS on your Windows computer.
If you want to restore those of your Internet provider instead, follow the same procedure I indicated and check the box Obtain DNS server address automatically, in the Property at the entry Internet Protocol versione 4 (TCP / IPv4).
To make the change immediate, you will need to clear the Windows DNS cache and that of your browser.
Open the Command Prompt Windows as administrator and type the following ipconfig / flushdns to clear the Windows DNS cache. To clear your browser cache, refer to this guide instead.
How to Set Up OpenDNS on MacOS
On devices with macOS operating system, you can change DNS servers, reaching the System preference (by clicking on the appropriate icon in the bar Dock) and selecting the voice Network from the window that just appeared to you.
Then select the first item that is shown to you from the left bar, which corresponds to the current connection in use (Ethernet or Wi-Fi). Then click the button Advanced that you find at the bottom right. At this point, select the tab DNS and empty the list you find in the box DNS server, using the button with the symbol [-]. Then press the button [+] and enter the OpenDNS DNS. The addresses to enter are the following:
If you want to use OpenDNS DNS instead designed to block adult sites (Familyshield), you can type the ones below:
When done, click the button Ok and then on the button Apply.
If you want the DNS to be acquired by the system immediately, you will need to clear your browser cache (you can read my guide on how to clear the cache) and then you will have to clear your macOS DNS cache.
If you have a macOS from version 10.9, open the terminal and type the following commands:
sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder
How to Set Up OpenDNS on Android
On mobile devices running Android, you can set up DNS on the Wi-Fi network you connected to. If you want to change the DNS on the data network, then you will need to have root permissions on your device; you can then deepen this topic through this guide of mine.
Returning instead to the question of changing the DNS on the Wi-Fi network, I invite you to pay attention to the procedures to follow, so as not to have any problems in configuring OpenDNS on your smartphone. I remind you that the procedure that I will show you may be different depending on the model and brand of your Android device.
Open the Settings Android and select the item Wi-Fi. In the newly displayed screen, you will see all the Wi-Fi networks available around you. Find the one you are currently connected to and hold your finger on it so that a context menu appears.
Then tap on the item Edit network and select (or expand) the option Show Advanced Options. You will then have to tap on the item IP settings and select the value Static. New items will then appear on the screen, which you will need to scroll through until you find the items DNS 1 e DNS 2. Fill in these two fields with the following addresses:
DNS 1: 184.108.40.206
DNS 2: 220.127.116.11
To use OpenDNS DNS filtering adult content, you can type these others instead:
DNS 1: 18.104.22.168
DNS 2: 22.214.171.124
You will also have to fill in all the other items you see on the screen and then press the button Save.
How to Set Up OpenDNS on IPhone / IPad
The procedure for setting OpenDNS DNS on Apple mobile devices is just as easy. Again, you will need to reach the Settings of iOS, by tapping on its icon with the symbol of a gear.
Next, tap on the item Wi-Fi and find the Wi-Fi network you are currently connected to. Then tap on symbol [i] that you find alongside.
In the screen that opens, tap on the item DNS and type the DNS server address of OpenDNS. Then type the ones I propose below:
To use DNS Familyshield of OpenDNSS to block adult content, use the following instead:
To save the changes, tap on the item Wi-Fi top left. From this moment on, the DNS used will be those of OpenDNS.
If instead you want to change the DNS for the data network, know that it is not possible to do this on devices with iOS.
