Include peer IDs on the DHT?

[pfrazee]

"Peer IDs" are used solely to deduplicate connections. If they were present on the DHT, we could avoid even attempting to connect to a peer which we've already connected to.

Things to consider:

• Could choosing peer ID be used to attack somebody? Eg, announce under somebody else's peer ID to effectively DoS them.

We could use hash(IP + port) for the Peer ID so that they're not choosable.

[pfrazee]

Though- if we're using hash(IP + port) that's information we already know. We already avoid connecting to IP/ports that we're already connected to.

Peer IDs are supposed to be a way to detect when the peer is == when the IP/port is different, eg due to ipv6 vs ipv4 or public vs lan, right?

i think we can choose that options， default is ID open on DHT

Is this the reason why the @next version removed the deduplication logic from peer-info ?
