And if no torrent provides valid/existing nodes
then we will fail to connect to the DHT.
I think you have a misguided concern for privacy here. In the DHT you literally advertise your IP and say "hey guys I have these torrents to offer" and you associate your IP with a bunch of infohashes.
But for you to enter the DHT you have to start from a known node/participant of the DHT. Connect to it and work your way into your correct place in the DHT (network topology IIRC).
The above routers (eg router.bittorrent.com
) provide a quick and easy way to enter the DHT (aka bootstrapping). They reply to you a bunch of DHT nodes and disconnect from you. Then you use those nodes to connect further into the DHT.
I think the warning they have put into the BEP was so that the router (aka server) won't get overloaded by a multitude of requests.
Is this ignoring the proxy/VPN ip settings and instead reporting the real ip address to the DHT servers?!

This is handled by libtorrent. I assume that it will use the configured proxy. If it doesn't then it is a bug. Same goes for the VPN.
the nuance is just that it should only happen when no prior DHT clients are known

Reading from libtorrent doc it is already done this way:
This is a comma-separated list of IP port-pairs. They will be added to the DHT node (if it's enabled) as back-up nodes in case we don't know of any. This setting will contain one or more bootstrap nodes by default.
DHT may be passing internal ip address for similar reasons that this happens: 4.1.5 send internal ip to tracker if network interface selected https://github.com/qbittorrent/qBittorrent/issues/10051
Hello. Hello 👋. NextDNS is blocking dht.aelitis.com. Should I place it on the DNS allowlist? . Thanks!
Is this an upstream libtorrent issue then ?
qBittorrent version and Operating System
all that i can see
What is the problem
DHT doesnt follow specification
What is the expected behavior
only using discovered nodes to seed DHT
Steps to reproduce
use DHT
Extra info(if any)
using DHT contacts centralized servers to seed for peers, this leads to zero privacy for the qbittorrent users
