我在哪里可以找到bittorent dht bootstrap节点的列表？

Question

Using my google-fu I was able to find only a few nodes:
router.bitcomet.com, router.utorrent.com, router.bittorrent.com

Is there somewhere a list of all bootstap nodes which I'm not aware of? Where do the torrent client developers get addresses of the bootstrap nodes? (I've looked at deluge source code and seen the modes above hardcoded.)

Answer 1

so far i have got these.

session = lt.session()
session.listen_on(6881, 6891)

session.add_dht_router("router.utorrent.com", 6881)
session.add_dht_router("router.bittorrent.com", 6881)
session.add_dht_router("dht.transmissionbt.com", 6881)
session.add_dht_router("router.bitcomet.com", 6881)
session.add_dht_router("dht.aelitis.com", 6881)
session.start_dht()

Answer 2

Those are the only bootstrap servers I know of. Note that router.bittorrent.com is just an alias for router.utorrent.com.

uTorrent just uses router.utorrent.com as its bootstrap server, and I imagine most other clients do as well.

If you have a specific client you're interested in know what it bootstraps off of, you can always wireshark its DHT traffic (from a fresh install) and see where its first DHT packet is sent.

If you have any torrents, the router is not very important, since you can also bootstrap off of normal bittorrent peers.

Answer 3

You initialise from a well known nodes as you mentioned above, ie "router.bittorrent.com:6881"

Then it's up to the DHT client to keep a track of nodes from thereon in.

There is nothing stopping you from saving your routing table between sessions, though many of these nodes are likely not to be running the next day.

Since you're supposed to maintain the routing table, you may want to keep an eye on the nodes with the longest uptime and persist those between sessions.

With my own tests DHT startup (until a reply to find_node, returns your node) is pretty quick from cold start.
