Among the documents that the "most likely North Koreans", according to the US, attacked from the Sony Pictures Entertainment there was a lawyer's appeal addressed to the Film Producers Association (MPAA). In the memo, a method is proposed to make Internet Service Providers (ISPs) responsible for piracy if they do not remove pirated root sites, that is, from the servers that "understand" their name, namely DNS servers under their supervision.
Κάθε εταιρεία 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 apparently proposed that the Union attempt to narrow the definition of DNS servers as "indexes" in order to compel ISPs to comply with the dictates of copyright holders, 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, experts comment on The Verge, would endanger users and would make ISPs susceptible to bogus/fake takedown requests to sites that appear to be hosting copies of copyrighted material in the absence of legal process.
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.
