Dht-bootstrap is an implementation of a bootstrap node for the BitTorrent (mainline) DHT. Rather than maintaining a Kademlia routing table, it performs a partly random, partly breadth-first walk of the DHT, and maintains a window of the last 255 reachable nodes that it encounters. It replies to find_nodes and get_peers requests with a random subset of the reachable window. Thanks to Greg Hazel for the initial idea. Juliusz Chroboczek
