try this, not really sure what dht is but had a look arond. hope it helps!
dHT(Distributed Hash Table) is method of a distributed storage for <key,value> pairs. There is no center server in DHT Network, every client take charge of a small range of routing, a small set of data storage, so that in the whole DHT network, data can be found, read and write. The new version of BitComet can connect to Tracker and DHT network, that means file can be download even if all trackers can not be connected. The protocol of DHT Network in BitComet is compatible with BitTorrent Beta 4.1.2, so that they can share the same network. Please note that the DHT in Azureus is not compatible with BitTorrent Beta and thus also not compatible with BitComet.
The DHT algorithm we use is Kademlia ( called KAD in eMule, but the network protocol is different from bittorrent. ) You can find more about DHT network here: http://en.wikipedia.org/wiki/Distributed_hash_table
