Among the documents that the "most likely North Koreans", according to the US, attacked from the Sony Pictures Entertainment there was a legal memo addressed to the Motion Picture Producers Association (MPAA). The memo suggests a method to make companies that provide access on the Internet (ISP) jointly responsible for piracy, if they do not remove the pirated sites from the root, that is, from the servers that "understand" their name, i.e., the DNS servers under their supervision.
Each company που παρέχει πρόσβαση στο Ίντερνετ διαθέτει και διακομιστές DNS. Κάθε φορά που ο συνδρομητής πληκτρολογεί μια διεύθυνση στον browser, ο DNS server πιάνει δουλειά, σε μια προσπάθεια να κοιτάξει στους διακομιστές DNS του ISP για να βρει σε ποια αριθμητική διεύθυνση (IP address) αντιστοιχεί η διεύθυνση αυτή και να δρομολογήσει το αίτημα στον προορισμό του. Εάν δεν την βρει στην δική του βάση, ο server becomes a client and asks the server higher in the hierarchy to find the IP address requested by the subscriber, reaching even the highest level, that of the famous 13 servers of the DNS system, which contain the database of all names and addresses in the entire Internet.
When it finds its address, the server takes a number of actions, such as routing the traffic to and from the subscriber.
In Sony's memo, it is fawater that it is proposed that the Union attempt to narrow the definition of DNS servers as "indexes" to compel ISPs to comply with copyright holders' orders without a court hearing. Otherwise they will be liable, secondarily, for their contribution to their subscribers' access to product of copying protected content.
Such a practice could create a black market for DNS, expert commentators at The Verge would endanger users and make ISPs prone to false / forged requests to remove access to websites that will appear as a copyhouse protected material, absence of legal proceedings.
However, although the practice has been debated and rejected by the US Senate a few years ago, the memo to the MPAA dates back to 14 August 2014 and proves that Sony has not abandoned its attempt to bring another blow to uncontrolled dispersal copies of movies, without hesitating to use tactics that would even hurt the way one finds his way on the Internet.
