questions about the bep44

[ac169]

libtorrent project is a rare implementation of BEP44 Protocol library, I use c language to achieve DHT (BEP 44) Protocol encountered some problems, the official document is relatively simple, there are a few questions to consult

1. put message Indicates the flow of sending messages without ping -> find_node -> get_peers as long as the peer ip address and port are known.

2. put message Whether the token parameters in the request parameters are generated by the requestor or obtained through get_peers first. The nodes returned by get_peers may have multiple tokens but only one token, so how to correspond is a bit confusing.

3. Is there any official or other third party to provide test nodes, or other ways to facilitate debugging of this protocol?
