Find out how nations prevent their citizens from accessing certain websites
Surely you have heard a lot about countries that block certain sites on their citizens and thus prevent them from accessing them, but you have not heard or have an idea about the ways in which the governments of these countries block these sites, and on this basis in this post I will try to convey this idea to you, as there are several methods that are followed, but some of them remain the most used, and I will share them with you in this new topic.
1- FIRST: AUTONOMOUS SYSTEM NUMBER
This method is followed in extreme cases. It is known that many users, when blocking a particular site, use proxy and VPN programs to bypass this blocking, but through this method, when a country asks the service provider to use it, it will not work with it, neither a proxy nor anything else, as the site remains blocked no matter what users do. But how does this method work?
AUTONOMOUS SYSTEM NUMBER, WHICH IS SYMBOLIZED BY THE ABBREVIATION ASN, IS A PROTOCOL SYSTEM USED IN RECEIVERS AND INTERNET DISTRIBUTION, WHICH IS THE ROUTER IN ANY HOME, FOR EXAMPLE, WHEN THE SERVICE PROVIDER WANTS TO BLOCK A CERTAIN SITE, IT WORKS IN THIS WAY TO DIRECT THESE SITES TO IT WHEN THEY ARE REQUESTED FROM USERS, THEN THE PATH IS CHANGED TO ANOTHER DIFFERENT, AND EVEN UNDERSTAND MORE, FOR EXAMPLE, IF YOU REQUEST A https://www.masrawysat111.com SITE, IT IS ASSUMED THAT THE BROWSER YOU USED IN THIS PROCESS SENDS
This data is sent to the router, then the router sends it in turn to the service provider, and so in the event that the https://www.masrawysat111.com site is blocked from the country itself, it directs the path to a blocked page and thus prevents access to this site even if you use proxy programs.
2---The second way. Putting the IP and the name of the site in the block
list This method, as it came from its title, the service distributor, after receiving orders from government agencies to block a specific site, takes the IP of this site and its name, and then it is placed in one list, and this method can be skipped using IP change programs, by virtue of the fact that they are not directed to the service provider when requesting these sites, which allows to bypass the block simply unlike the first more complex method .
It is worth noting that there is another method that is not used much in blocking sites through the top-level domain feature, which depends on blocking domains, for easy bypassing blocking without programs, and I hope that you have taken even a simple idea of this point.
