Technically, localhost is a domain name that, on almost all modern systems, resolves to the IPv4 loopback address 127.0.0.1 and the IPv6 loopback address ::1 . The entire 127.0.0.0/8 address block (from 127.0.0.1 to 127.255.255.255 ) is reserved for loopback purposes. This means any data packet sent to any of these addresses is immediately looped back to the same machine. This is a powerful feature, as it allows you to run and test network services without ever needing an active physical network connection.
