1、首先找到host文件：C:\Windows\System32\drivers\etc
2、打开host文件：
1 # Copyright (c) 1993-2009 Microsoft Corp. 2 ## This is a sample HOSTS file used by Microsoft TCP/IP for Windows. 3 ## This file contains the mappings of IP addresses to host names. Each 4 # entry should be kept on an individual line. The IP address should 5 # be placed in the first column followed by the corresponding host name. 6 # The IP address and the host name should be separated by at least one 7 # space.## Additionally, comments (such as these) may be inserted on individual 8 # lines or following the machine name denoted by a \'#\' symbol. 9 ## For example: 10 ## 102.54.94.97 rhino.acme.com 11 # source server 12 # 38.25.63.10 x.acme.com 13 # x client host 14 15 # localhost name resolution is handled within DNS itself. 16 # 127.0.0.1 localhost 17 # ::1 localhost 18 0.0.0.0 account.jetbrains.com
3、找到 38.25.63.10 x.acme.com ，注意#为注释，在下方添加新的

4、进行cmd，ping发现指向127.0.0.1
