Still, would a mining pool show up as an individual node or a bunch of nodes?  Afterall, all nodes would be communicating through one mining node, right?

<p>Any ideas for finding the number of Bitcoin nodes vs the number of Bitcoin pools?</p>

<p>Thank you!</p>

Does getaddr.bitnodes.io find all Bitcoin nodes or only one node per mining pool?

getaddr.username_1.io shows only the reachable Bitcoin nodes in the network. These are nodes that make up the core data exchanges within the P2P network.

There is non-trivial distinction between mining and non-mining nodes at the protocol level among the network participants. Although having observed the first announcement of a block from a node may be a good indicator of a mining node.

It is impossible to tell the full size of the network that includes nodes behind firewall, or nodes that only accept connection from certain IP address/netblock, or nodes that have simply hit the set max. connections.
