That part admittedly is above my understanding. I did not know the process. It would seem a central hub would have to gather it.
Thanks!
yes and no. There are numerous 'tracking servers' that keep track of torrent locations. When someone downloads a torrent the tracking server gathers all the locations sharing that torrent and then pulls small portions from each 'seeder' and send them to the downloading location.
This is how the plaintiff is getting their "IP" information I imagine. Whoever happens to be online and sharing that file at the time they take their 'snapshot' of IP's will be their targets.
