Bitnodes is currently being developed to estimate the size of the Bitcoin network by finding all the reachable nodes in the network.
Activate node status for [2406:e000:6df9:4c01:a85a:552e:a037:e981]:8333 and receive alerts by associating one or more contact information with this node.
Be part of the Bitcoin network by running a Bitcoin full node, e.g. Bitcoin Core.
Use this tool to check if your Bitcoin client is currently accepting incoming connections from other nodes. Port must be between 1024 and 65535.
