  • I don’t believe this is possible and actively protected against in the dht protocol implementation.

    The return value for a query for peers includes an opaque value known as the “token.” For a node to announce that its controlling peer is downloading a torrent, it must present the token received from the same queried node in a recent query for peers. When a node attempts to “announce” a torrent, the queried node checks the token against the querying node’s IP address. This is to prevent malicious hosts from signing up other hosts for torrents. Since the token is merely returned by the querying node to the same node it received the token from, the implementation is not defined. Tokens must be accepted for a reasonable amount of time after they have been distributed. The BitTorrent implementation uses the SHA1 hash of the IP address concatenated onto a secret that changes every five minutes and tokens up to ten minutes old are accepted.

    I believe you would have to know the torrent first, then you could discover other nodes. This is probably why that tool can’t tell you anything outside of it’s known list of torrents.
