Questions tagged [hosts-file]

The hosts file is a computer file used in an operating system to map hostnames to IP addresses. The hosts file is a plain text file and is conventionally named hosts.

The hosts file is one of several system facilities that assists in addressing network nodes in a computer network. It is a common part of an operating system's Internet Protocol (IP) implementation, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, that identify and locate a host in an IP network.

In some operating systems, the hosts file's content is used preferentially to other methods, such as the Domain Name System (DNS), but many systems implement name service switches (e.g., nsswitch.conf for Linux and Unix) to provide customization. Unlike the DNS, the hosts file is under the direct control of the local computer's administrator.
