    # Copyright (c) 1993-2006 Microsoft Corp.
    #
    # This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
    #
    # This file contains the mappings of IP addresses to host names. Each
    # entry should be kept on an individual line. The IP address should
    # be placed in the first column followed by the corresponding host name.
    # The IP address and the host name should be separated by at least one
    # space.
    #
    # Additionally, comments (such as these) may be inserted on individual
    # lines or following the machine name denoted by a '#' symbol.
    #
    # For example:
    #
    #      102.54.94.97     rhino.acme.com          # source server
    #       38.25.63.10     x.acme.com              # x client host
    # localhost name resolution is handle within DNS itself.
    #       127.0.0.1       localhost
    #       ::1             localhost

What's the Hosts file

The Hosts file is a computer file that is used by the operating system to map hostnames to IP addresses. 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 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.

The Hosts file contains lines of text consisting of an IP address in the first text field followed by one or more host names. Each field is separated by white space (Tabs are often preferred for historical reasons, but spaces are also used). Comment lines may be included, and they are indicated by a hash character (#) in the first position of such lines. Entirely blank lines in the file are ignored.
