Ahh ok, makes sense. Are there also other types of nodes (not affiliated with Umbrel) that are missing from this network map?
I've seen some articles like this (https://bitcoinist.com/bitcoin-network-surpasses-100000-nodes-new-data-shows/) claiming there are 100,000 nodes... but not sure what the distinction between listening nodes and reachable nodes is.
Are the two mutually exclusive?
I do suspect the map is incomplete. Reachable nodes are very likely to be in the minority of nodes given the way routers work - it requires additional configuration explained here https://bitcoin.org/en/full-node#enabling-connections.
Listening and reachable mean the same thing in this context - they accept/listen/can receive incoming connections from peers. In contrast, unreachable/non-listening nodes establish only outgoing connections to peers.
