The hosts file is a setting file for the correspondence between the IP address and the host name, and is used when there is a correspondence that you want to use only on a specific computer. For example, it is used when connecting to the test server with the same host name as the production server on the development personal computer. The correspondence is described as "IP address (space or tab) host name" (example: "127.0.0.1 localhost").
