Report to the authorities

Use the cmd command (cmd you should know ... friend)

Type ipconfig at the command prompt to view the network configuration of this machine, where "IP"

The number after "Address" is the IP address of your computer. Of course, if you want to know the more detailed configuration of the machine, you can add /all after it, which is ipconfig/all.

Type netstat at the command prompt.

-a You can see the open ports of this machine. If you change the -a parameter to -n, you can see the network connection of the port.

You can understand an ip address as a house number, so that others who want to access your computer can find you through the house number.

Port? How can I put it? Generally speaking, opening a service on a computer will open a corresponding port, such as port 80 for http protocol, port 2 1 for FTP protocol and port 3389 for remote use.

The above is just a personal understanding, and there are still many mistakes to be corrected.
