Directly to the solution, the steps are as follows:

  • 1. Through the domain name query IP, site.ip138.com/github.com/
  • 2. Add the correct IP address and domain name to C:\Windows\System32\drivers\etc\hosts

It should be noted that this IP address is frequently changed, so when the access is not possible to change the new IP address on the line. Access to Github does not need to climb the wall, but cannot be accessed because the domain name has been resolved to an incorrect IP address.
