BitTorrent is also a nightmare for ISPs due to its network agnostic nature, which is responsible for high network transit costs. The research community has deployed a number of strategies for BitTorrent traffic localization, mostly relying on the communication between the peers and a central server called tracker. However, BitTorrent users have been abandoning the trackers in favor of distributed tracking based upon Distributed Hash Tables (DHTs). The first contribution of this paper is a quantification of this claim. We monitor during four consecutive days the BitTorrent traffic (both tracker-based and DHT-based) within a large ISP. The second contribution of this paper is the design, prototype, and preliminary evaluation of the first traffic localization mechanism for DHT-based BitTorrent networks. %G English %Z TC 6 %2 https://inria.hal.science/hal-01597986/document %2 https://inria.hal.science/hal-01597986/file/978-3-642-20798-3_4_Chapter.pdf %L hal-01597986 %U https://inria.hal.science/hal-01597986 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC6 %~ IFIP-NETWORKING %~ IFIP-LNCS-6641
