The hosts file is one of the features of several systems to assist in addressing point nodes on computer networks. It is part of an implementation of the Internet Protocol (IP) operating system, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, which identify and locate hosts within an IP network.

In some operating systems, the hosts file content is used over other methods, such as Domain Name System (DNS). But many systems implement name service switches (eg: nsswitch.conf) to provide customization. Unlike DNS, the host file is under the direct control of local computer administrators.

Windows Host File Contents
The hosts file contains lines of text consisting of IP addresses in the first text followed by one or more hostnames. Each field is separated by a space. A comment line can be entered by adding a hash character (#) in the first position of the line. Here is an example:

# This is an example of the contents of the hosts file localhost loopback
:: 1 localhost

Above is the default instance of the contents of the hosts file, The example specifies that the IP address may have multiple hostnames, and the hostname can be mapped to multiple IP addresses.
