# Copyright (c) 1993-1999 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
127.0.0.1    localhost
上述文字是原件内容，实际上#的都是注释文字，起作用的就最后行。
