部分情况下，hosts文件出现异常、丢失等情况。

可以参考以下方法进行还原出厂默认hosts。

为了以防万一，可以提前备份hosts文件C:\Windows\System32\drivers\etc

CMD管理员身份运行如下命令：（提示覆盖输入yes）输入完成之后需要等待一段时间

for /f %P in ('dir %windir%\\WinSxS\\hosts /b /s') do copy %P %windir%\\System32\\drivers\\etc & echo %P & Notepad %P

也可以直接复制粘贴如下文本到hosts文件

+# 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
