The Internet cafe, library, or private business from which you work may determine which computer you are using at which time, and which wireless port or access point you are connected to. Government agencies can easily obtain this information because of their influence on these organizations. With elo job the deal has come to a completion for gaming.
At this point, your ISP relies on the existing network infrastructure in your country to connect its users, including you, to the rest of the world. At the other end of the connection, the site or Internet service you accessed had to go through a similar process, which also received IP addresses from an ISP in the country where it is hosted. Even without more technical details, a simplified model like this one can be useful to you to take into account the various tools which make it possible to circumvent the filters while remaining anonymous on Internet.
How Are The Websites Blocked?
In some cases, it is a central agency, not the ISPs, that deals with filtering. Most of the time, a “blacklist” contains domain names, rather than IP addresses. In some countries, filtering software will control your connection instead of blocking your access to specific addresses. This type of program scans all the queries you make (and all Internet sites that try to answer you) to detect certain keywords and, depending on its conclusions, decide whether or not you can see the results of your queries.
Worse, when a website is blocked, you may not even know it. These messages indicate that the page cannot be found, for example, or that there is an error in the address.
In general, when it comes to censorship on the Internet, it is simpler to adopt a downright “pessimistic” attitude than to carefully study all the fortes and flaws of the riddling skills castoff in your state. In other words, you should take it for granted that:
- Someone controls your activities on the Internet to detect certain keywords;
- Filtering occurs directly at the ISP level;
- The blocked sites are blacklisted according to their IP addresses and their domain names;
- It is likely that you will be given an ambiguous or misleading reason why the connection to a particular site has failed.
Since the most effective workarounds can be used against either of these filtering methods, it is actually quite useful to adhere to these “pessimistic” assumptions.
So, if one day or another you cannot access the blog, but a friend in another country still manages, does that mean that the government has finally managed to block it?
Not necessarily. It is possible that a problem of a different kind only affects users who are trying to reach the site from here. It can also be a problem with your computer that only occurs with certain types of web pages. That said, you are on the right track. To be clear, you should try to visit the site using a bypass tool. After all, most of these programs rely on the use of external proxy servers, which is about asking a friend abroad to test the site for you, except that you do it yourself.
