For the DHT protocol, there are four **queries**:
- `ping`: to check if another node (one from its DHT routing table) is online and reachable,
- `find_node`: find the contact information for a node given its ID,
- `get_peers`: get peers associated with a torrent [[Infohash|infohash]],
- `announce_peer`: to *announce* that the peer, controlling the querying node, is downloading a torrent on a port.
