　　# 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 handled within DNS itself.

　　# 127.0.0.1 localhost

　　# ::1 localhost
