Windows modifies the host file

In real-world development, we sometimes modify the Windows Hosts file to achieve the ability to map the specified domain name to the specified IP. Modify the method as follows:

1. The Hosts file location in Windows (WIN10):

C:\Windows\System32\drivers\etc\hosts

2. How to Modify

#将www. aaa.com domain name mapped to 127.0.0.1 IP address 127.0.0.1   www.aaa.com

　　

3. Application

Without rebooting the system , after applying the modified Hosts file, open cmd and enter the following command:

3.1 Viewing DNS cache content

Ipconfig/displaydns

　　

3.2 Remove the DNS cache content to achieve DNS update purposes

Ipconfig/flushdns

　　

4. Access to custom domain name testing
