1、首先找到host文件:C:\Windows\System32\drivers\etc
2、打开host文件:
# 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
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
