How do I stop accessing the site?

It's no secret that despite all the benefits,which brought the Internet, it became a worldwide garbage, because anyone can open their site and put everything they want on him. On this garbage can find real diamonds among rubbish, but there are also harmful, dangerous, porn and other sites. And there are very fascinating sites on which both adults and children hang to the detriment of work, study and even health. Therefore, many employers, parents and other users want to know how to block access to the site.

Browsers

This can be done for a specific browser. For example, for Internet Explorer, you need to go to Internet Options, open the Content tab, select Restrict Access - enable. In the window that opens, you can set a restriction on age categories, and also allow or deny access to any site. In the Opera browser, go to Tools, then Advanced, then Locked content. In the window that opens, you can enter all the sites you want to block.

Similar possibilities exist in all browsers, but nothing prevents the user from downloading the browser version from the USB flash drive and bypassing all these restrictions.

Hosts file

You can stop access to certain sites fromusing the hosts file. You can find it by following the path C: WINDOWSsystem32driversetc. In the folder etc there is this file. It is used to map ip addresses to the names of known sites. Usually, the computer requests this from the DNS server, but if this information is in the hosts file, it will not do this. Here, for example, are some correct comparisons:

213.180.193.11 yandex.ru

87.240.131.100 vk.com

213.232.249.155 freelance.ru

87.240.188.252 vkontakte.ru

You can open the file using Notepad. Usually, if no one has edited it, including an evil virus, it contains several explanatory notes that begin with the # at the beginning of the line. At the very bottom there is usually a record:

127.0.0.1 localhost
:: 1 localhost

localhost is the computer itself. If there are also # icons in front of these lines, they need to be removed. Now you can add the necessary (rather unnecessary sites) by matching them with the same ip-address, for example:

127.0.0.1 vkontaktesvami.ru

127.0.0.1 por.ru

127.0.0.1 teryra.com

In one line, first write the ip-address, then -Name of the site. There must be at least one gap between them. After the # icon, you can add a comment. After that, you need to save the fixes from the File menu and restart the browser. When you access one of these sites, the computer will look for them in itself, and the browser will display a blank page.

By the way, you can write the ip address of any other site instead of 127.0.0.1. For example, if we write

84.52.123.191 vkontakte.ru

instead of the site "Vkontakte" will be loaded siteelhow.ru. Do not just forget that you can edit the hosts file every user with administrator rights, so you need to make sure that those for whom restrictions are imposed have the rights of ordinary users.

In contact with

Close access to VKontakte, which, by the wayspeaking, moved completely to a new address vk.com, it turns out, somewhat more complicated. The fact is that a lot of resources have appeared that provide alternative access to this site, as well as to classmates and other similar sites. They can be tracked on resources such as Access, Ban, Net, and the like. Here is a far from complete list of addresses on which you can get to the site "Vkontakte":
