The solution is there and to apply it you don't necessarily have to be a computer expert, just follow what I'm about to tell you carefully.



The first thing to do is edit the file hosts of Windows that you will find in the path c: WindowsSystem32driversetc.

The function of the hosts file is to make browsing faster by storing the correspondence between IP addresses and domains. In this way it will not be necessary to query the DNS server, which normally takes care of this operation.

By eliminating one step, the connection will be much faster.

HOW TO BLOCK ACCESS TO THE SITES FROM THE PC

Write Block notes or notepad in the Windows search bar and select the program with the right mouse button. From the menu that appears choose Run as administrator.

In the window apri, move to the folder . and sets All files (*. *). You will see several documents appear, including the file hosts. Open it and scroll to the end of the hashs (#). Enter the IP address 127.0.0.1 and the address of the site to be blocked.



For example 127.0.0.1 www.facebook.com.

If you have a Mac, you can edit the hosts file on Mac OS X in two ways: app text Edit or through terminal.


To edit hosts file on Mac OS X you need to open Text Edit and go to the folder "private/etc/hosts". As with Windows, the hosts are also blocked on Mac OS X. You will need to make a copy for yourself.

To do this, right click on the original hosts and make a copy. Edit the file and save it by replacing the old hosts file with the new one.

The second method you can use to edit the hosts file on Mac OS X is through the Terminal. In the editor of the terminal finger nano /private/etc/hosts. Once the hosts file is open, edit it with the same information contained in the Windows hosts and press when finished CTRL + X to save and close the file.
