How to block a site

How to block a site? Such a question sooner or later arises in all people who have access to the World Wide Web. Parents can get bored that the child always sits in classmates. The boss, who repeatedly found employees during working hours for reading news, may also need some way to limit the activity of users. If you have young children growing up, then you hardly want them to be on the pages of the category XXX, which are now apparently invisible, which means that you too may be interested in the question of how to block adult sites.

I hope that this material will supplement your knowledge of the possibilities of the computer and give you a couple of ideas on how to correctly organize access to the network for your children or employees.

Let's try to find out first how to block a site that you do not like. Let's say that your young children, you need to step outside the door, immediately sit down at the computer and disappear on the site miniclip.com

To start with a bit of theory, the alphabetic designations of sites are convenient for people, but computers communicate with each other through numbers. So, typing in the address bar of your browser www.miniclip.com, you use a computer to send a request to a special DNS-server to visit this site. The computer from the DNS server receives a response about this content www.miniclip.com = 77.73.36.123, this set of digits is the digital address of MiniClip.com, the digital combination in the address is at each site. By the way, by typing these numbers in the address bar , you will also get to the site in question, as if you typed an alphabetic address.

Now that you have a little idea of how the World Wide Web works, let's move on to the next point.

At the address: // windows / system32 / drivers / etc / hosts, (the C drive and the windows folder must be replaced with that drive letter and then the directory name in which you have the operating system installed), you can see the hosts file, note that This file does not have an extension, so the default system does not know how to open it. The most convenient way to open this file will be a normal notepad, with which you can immediately make the necessary adjustments to it. For lazy people, there's an easier way to Start> Run> copy the line

Notepad% windir% \ system32 \ drivers \ etc \ hosts. Voila, you have opened the hosts file for correction. How can I block a site using the hosts file?

If you open the "hosts" you will see the text preceded by the # symbol - ignore it, the system ignores all lines beginning with a sharp one. But in the end there will be what we are looking for, there you will find the line 127.0.0.1 localhost.

If you want, that without you it was impossible to go to the site minilip, add after line 127.0.0.1 localhost with the following line 127.0.0.1 miniclip.com

If you do everything correctly, do not forget to save the changes and restart your computer, then when you try to access this site you will get an error "address is not available". That's all the wisdom and now, when you already know an easy way how to block a site that you do not like, you probably have a question, but what if you want to block several sites?

I would not recommend a hosts file for such experiments, since a large number of entries in it can negatively affect the operation of the web browser. In the case where you want to block a large number of resources, you should choose either specialized applications like "K9 Web Protection" or go against the opposite - forbid using a firewall (for example, free "ZoneAlarm") everything, and give access only to those sites that You trust. So it will be much easier and more reliable. By the way, if you download and install this program and spend a little time studying its interface and capabilities, you will not only learn how to block the site or the entire Internet with Zone Alarm, but also significantly reduce the vulnerability of your computer for possible attacks from the network.
