Overview#Localhost is 127.0.0.1 on the local device.
Localhost is a hostname that means this computer.
The local loopback mechanism is useful for testing software during development, independently of any networking configurations.
For example, if a computer has been configured to provide a website, directing a locally running web browser to http://localhost may display Localhost home page.
Localhost is also a reserved Top-Level Domain name, set aside to avoid confusion with the definition as a hostname. The IETF standards restrict domain name registrars from assigning the name Localhost in registration procedures. (RFC 6761)
