This is a feature of "BitTorrent DNA," although I don't know how it was implemented. I also know that Azureus/Vuze figures out the AS number of its host, purportedly for a upcoming feature (so it can find peers on the same AS?). Bizarre fact -- Comcast interrupts Comcast-to-Comcast transfers, even those that never leave the Comcast network! And the irony to this fact is the effect that it has: it makes the least expensive pairings twice as likely to get interrupted! -- Robb Topolski
