Shows the total number of reachable A node is considered reachable when a connection to it could be established. Bitcoin nodes, independent of network type Network type refers to the network protocol used to establish a connection. Network types currently taken into account are IPv4, IPv6, Tor (v3), I2P. .

More metrics concerning unique unreachable nodes are available via the navigation sidebar and include:

• Number and share of reachable nodes by network type
• Number and share of reachable nodes supporting various network services
• Number of long-term reachable nodes
• Monthly change of total, IPv4, IPv6, Tor (v3), and I2P reachable nodes

To learn about the methodology used to estimate the number of unique reachable nodes, see methodology in the sidebar.
