This diagram shows the number of peers currently participating at the BitTorrent-DHT. The depicted results are based on a extrapolation of a representatively chosen sample of peers within the DHT.

This diagram depicts the minimum, maximum and average DHT size measured on each day during the last year. While the strong diurnal fluctuation also seen in the previous diagram is responsible for the gaps between the three lines, the weekly fluctuation leads to the saw-like shape of each single line. In particular, the diagram also shows how the popularity of the BitTorrent Mainline DHT changed during the last year. Please note that most of the irregular looking peaks resulted from measurement errors due to ongoing maintenance of our measurement software. Please contact us if you have any questions regarding the plots. 

This diagram shows from which countries the observed peers originated from, regarding to their IP-adresses. The depicted results are based on the newest of the already mentioned and repeatedly chosen samples of DHT-peers. Thus, the diagram shows a snapshot of the current status of the DHT rather than a long-time analysis.

This diagram depicts the distribution of the port number used by the observed peers. If an observed peer is hidden behind a NAT router the external port number is used. The default port number of the BitTorrent-DHT is 6881. The depicted results are based on the newest of the already mentioned and repeatedly chosen samples of DHT-peers. Thus, the diagram shows a snapshot of the current status of the DHT rather than a long-time analysis.

This diagram illustrates, for what duration a peer was available until it did not respond to queries any longer. A data point (X, Y) has to be interpreted as: "After X hours, only Y% of the tested set of nodes has been available." The set of nodes is formed by nodes of one of the repeatedly collected samples, who were not part of the previous sample. Due to the implementation of the corresponding measurement algorithm, session lengths below 36 minutes are detected as being 0 minutes.

This diagram depicts the availability of peers commonly used for joining the DHT. These Bootstrapping Peers are usually contacted when users start their DHT client and now other peers are known yet and return other currently running peers to the client. Thus, Bootstrapping peers form a critical central component within the otherwise decentralized DHT network, as peers may not be able to join the DHT in case their configured or even hard-coded Bootstrapping Peers are currently unavailable. The diagram shows whether or not three of the most widely used Bootstrapping Peers did respond to DHT requests.
