JSON-RPC get full nodes information Is there any way to get all full nodes by RPC call?

Afaik full node contains information of other full nodes in the network and was wondering how to request that.

I red the documentation on Bitcoin Core Apis and all I found is getpeerinfo which returns a list of connected nodes but the JSON it gave me seem to not contain that information.

Does anyone know if this data is accessable and how to get it?
You cannot request this information, because it does not exist.

There is no central registry of nodes, nor do they have identities to begin with. Full nodes do maintain a database of IP addresses of peers they now about, but that is not, and is not intended to be, a comprehensive list of all nodes on the network.

The closest that exists are network crawlers who ask around for IP addresses and try connecting to them (some DNS seed report results based on crawler information), but even that is only an approximation, and can only discover nodes that are reachable. The vast majority of full nodes only make outgoing connections.
