How to obtain and change the local IP address of the module?

Q: how to obtain and change the local IP address of the module?

A: generally, obtaining the local IP address is mainly used for server communication and other purposes, which can be obtained by server software. If you want to obtain the local IP address through the serial port, this function is not available at present. To change the local IP address, you just need to re connect to the Internet, but you don't know the purpose of doing so.
