Localhost is a top-level domain designated for documentation and testing, just like. example, test, or. invalid. A loopback is started when attempting to access the domain. When you use the browser to view “http://localhost,” the request is not routed through the router to the internet. Instead, it will stay in your body. The IP address of the localhost is 127.0.0.1. This is a reference to your personal server.
