How can I block sites on my computer? Instructions for beginners

It may happen that you should restrict access to a certain site. There can be many reasons: the desire to focus on a certain project, and not to hang on some site, to limit the child's possibilities in researching the World Wide Web or something else. But how can this be realized? How can I block a site so that it does not open and no one can see its contents?

What does it mean to block sites on the computer?

Before answering the question of how to block a site so that it does not open, you need to answer one more question. First, what is a lock? This is the impossibility of accessing a particular network resource while maintaining the current working conditions. When you try to access a blocked site, you will see a message stating that the resource is temporarily unavailable or blocked. And the first option is preferable for the reason that people do not understand that it is blocked, and do not begin to look for an answer to the question of how to block sites on the computer and how to unlock them. In some cases, browsers offer standard solutions to overcome problems, which, as you can understand, do not help. But you will not be able to view blocked sites if you use the standard instructions.

Differences in scale

It's one thing to restrict access to sites on one computer. And a completely different level of complexity - restrictions in the whole network. So, for the first option, the best action is setting up on the computer itself. But in the second you can either bypass all computers in turn, or put a limit on the access point (router, server). Of course, the second option is more preferable for time costs. But if it requires part of the staff to leave the opportunity to freely visit all sites, then it will not work.

The easiest way

The simplest answer to the question of how to block sites on the computer is to edit the firewall file of the computer. Activate the search for files on the computer and enter the word hosts in the search string. The machine will show you the file on the C drive - it's what you need. Run it. Most likely, you will find that the computer could not determine what to open this file. Then right click on it and select "Open with." In the presented list of programs, look for the notepad and select it.

In the window that opens, reach the end of the file and enter: 127.0.0.1 address of the blocked site.

Save the file and close it. Access to blocked sites with such a file will not be available to the computer. A small note for the future: only a user with administrator rights can edit this file. And if you're afraid of spoiling something, you can make a copy of the edited file before making any changes to return access to blocked sites in the future.

Establishing a lock on the router

If there is only one computer, the previous version will completely satisfy all requests. And if you use a router and have the ability to visit different sites using tablets or smartphones? In this case, there is a lock on the router. Take the manual of your access point and look in it for information such as an Internet address, login and password. Enter the address found in the browser line, then in the appeared form - login and password. Then you will be available to the administration panel.

Once you are in the admin panel, you should look for the option of blocking domains. In many routers the way is: go to "Settings" and search for "Filtering" or "Domain Blocking". There must be an interface that allows you to resolve everything, except for certain domains. You should specify where you can not go, click on the application button and restart the router.

Locking with browser extensions

If the subject for whom the lock is being used uses Google Chrome or Firefox, then you can set a restriction in these browsers. To do this, you should go to the add-ons section and write something similar to the Site block or "blocking sites." And you will be shown the widest assortment of add-ons that will be able to block selected sites. This solution is a very good answer to the question of how to block sites on the computer, because few people have the idea to think about checking their extensions. To ensure that they have not been edited or disabled by another user, the extensions can be password protected. Despite the ease of installation, in this way there is one rather noticeable minus - if you delete the browser (and then install it) or the extension itself (from the folder where it is located), then protection is like it never happened.

Locks bypasses

But here's how to access the blocked site, access to which was restricted using previously mentioned methods? There are a lot of ways to circumvent the blocked locks. Some of them may not work in certain cases. Initially, you should remember about anonymizers - special sites that allow you to receive a response to the necessary requests. But the requests do not come from the user's IP address, but from the person of the anonymizer. Let's say someone asked himself how to block websites on a computer, and you want him to stand up against it. The scheme looks like this: you send data to a specific site. He sends them to the network resource, on which you want to visit. The answer comes to the anonymizer. And the information is redirected to you. The downside of this interaction is the lower data rate, but the main goal - gaining access - is performed. This, of course, is not an answer to the question of how to unblock a blocked site, but you will still be able to access it.

Also you can bypass the locks with the help of special software. One of the most famous is the browser "Thor". Its principle of operation is similar to an anonymizer with the difference that data is transferred not between the user and some server, but only between the users themselves, and they act as servers for other people. For example, everything will look like this: users of country A are prohibited from visiting site B, users of country B are prohibited from visiting site D. Users forward requests to each other, and the program makes a request from the recipient, then returns data to the one who is actually interested in them. But to use "Thor" should be wisely - in connection with the architecture of the program to hack it and send someone a virus, trojan or just to intercept data like login and password to the site - this is not the most incredible event.

Here are the two most popular answers, the choice in favor of which made millions, if not tens of millions of users, answering for yourself on the question of how to go to a blocked site.

White list of sites

But there is another option for blocking - creating a white list of sites. This option provides the creation of lists of addresses that can be accessed. Receiving or sending data to all others will be prohibited. Choosing the right software for you is simple, and the programs that are distributed for free and at the same time have the necessary functionality are great. Therefore, choose how to block sites on the computer, yet you.

Conclusion

The article examined various options for blocking access to various virtual resources, not only how to block sites on the computer, but also how to unblock them. If you like something, you can take advantage of your favorite option.
