很多人不知道hosts文件放在哪里？
C:\Windows\System32\drivers\etc
# Copyright (c) 1993-2009 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 handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

使用局域網(wǎng)代理的朋友需要注意：把改網(wǎng)址添加為不需要代理訪問。
chrome瀏覽器->設置->更改代理服務器設置->Internet屬性->連接->局域網(wǎng)（LAN）設置->代理服務器->高級->代理設置->例外
