Host addresses (127.0.0.1, 0.0.0.0)

Also written: 127.0.0.1, 0.0.0.0, loopback address

127.0.0.1 is the address a computer uses for itself (localhost), so a server bound to it accepts connections only from the same machine. 0.0.0.0 means every address the machine has, including its network card, so a server bound to it answers anyone who can reach the machine.
