How do I block access to the site?

Cases when it may be necessary to close access to the site, can not be called rare. For example, the user wants to close the child to a particular site, this can be a social network. At the same time, there is no need to download a specific program, which still has a long time to sort out. You can consider the most simple and effective way, which is to edit the system files hosts.

How do I block access to the site?

The file, which will be further considered, serves to prohibit the display in all browsers that are installed on the user's computer, as well as for professional configuration of local networks. This file often changes malicious programs. So, where is this file located? It is worth looking for on the system local disk, that is, what is under the letter C, and then you need to open the Windows folder in which you need to find the System32 folder. Inside this folder there should be a drivers directory, and in it you need to find etc, where the user will find the hosts file. In the event that it does not exist, this can only mean that you have been looking at it carelessly, since it is available on all computers running the Windows platform.

Blocking hosts sites allows you to block access from specific computers to specific sites. That is, a user or system administrator can prohibit the given PC from reaching certain domains. The hosts file is inherently a plain text file that is loaded into the cache when the system starts up, and when the system requests a DNS server, it checks this file. This file can be used to redirect the computer to another site or back to the local machine. You can even redirect the redirection from one site to another.

This file should be opened using Notepad. From there you can safely delete everything, after which you will have to determine which files should appear in the black list. Suppose you are interested in how to close access to the VKontakte site? This will require you to enter into the file:

127.0.0.1 vk.com

Before the site, this IP address must be registered, otherwise the lock will not work. After the computer is restarted, this site will no longer be available to it.

Before closing the file after editing, it is necessary to be convinced of something. The file should be in the same format as originally, that is, you can not agree to the offer of the system to assign it some format. At the beginning of the site address should not be added "HTTP", it is enough to write just WWW.

To return the accessibility of the blocked site, you must open the same file again, and in it delete the corresponding line, save it, after which the site will become available again.

Another way to block access to the site

This method involves closing access to the site from a particular browser. This can be, for example, Internet Explorer. To do this, you need to enter the properties of the browser, open the "Content" section, and select "Limit" access in it, then click the "Enable" button. Before the user will open a window in which you can allow or deny access to some sites, as well as set age limits. In the Opera browser, you can enter the "Tools", where you can find the "More" option. In this window, you need to open the "Locked content". In the window that opens, you can enter a number of sites that the user wants to block. This feature is available in every browser, however it is not as reliable as using the hosts file, since the user can download another version of the browser from the USB flash drive, or uninstall this browser, and then replace it with a new one.

So, now you know how to block access to the site.
