[Ethereum] How many nodes are there on the Ethereum network


When looking on the Ethereum Network Status site, only a limited number of nodes are listed. How can I discover how many nodes there are currently running in total?

Disclaimer: I run ethernodes.org

There is a node explorer available at ethernodes.org which tries to estimate the number of nodes on the Ethereum network.

The estimation is based on an active crawling process that recursively connects to a node and asks for its known peers. As this approach only reaches nodes that are accessible from the outside a second, passive approach is used to reach nodes behind a NAT.
