Most nodes sit behind a home router or firewall and never answer the crawler. Our sensors wait for them to dial in, then try to dial back. If the way back is closed, the node is private.

How a node gets classified
A node reaches a sensorThe sensor waits for a real incoming connection from another node.
The sensor dials backIt tries the address the node announced, then the address the connection came from, on port 16111.
It gets in: publicThe node accepts connections from that sensor.
The way back is closed: privateThe node counts toward the figures on this page.
