恢复方法（hosts 删了直接新建即可）
1. 进入目录：C:\Windows\System32\drivers\etc\

Win+R 快速打开 etc 目录
1. 按下 Win + R，弹出【运行】窗口
2. 输入下面路径，直接复制粘贴进去：
plaintext
 
 
 
C:\Windows\System32\drivers\etc
 
3. 回车，直接打开 etc 文件夹
注意：这个文件夹里面默认看不到 hosts 的 txt 后缀，记得在文件夹顶部【查看】选项卡，勾选 文件扩展名，才能正常修改文件名。
小补充
如果想直接用记事本打开 hosts（需要管理员）
Win+R 输入：
plaintext
 
 
 
notepad C:\Windows\System32\drivers\etc\hosts




2. 在 etc 文件夹内，新建文本文档，重命名为 hosts（删掉 .txt 后缀）
注意：修改 hosts 必须用管理员权限打开记事本，否则无法保存。
Windows 原版干净 hosts（空白模板，你可以备份）

 


文件名称:hosts
下方是文件内容:


 
# 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
