How to temporarily assign a device a specific IP address of another device. Do you have access to device 2?

Question

Computer networks

Well, or disguise. I do not know. The devices are located in different cities and have different Internet providers. Both poppies.

Answer 1

What address do you mean? Local or white? If local, then put what you want, it does not affect anything. The main thing is that from the same subnet, otherwise it will fall off the Internet. If white, that is static real external, then in any way.

Answer 2

Put a VPN or proxy server on the 2nd device and connect to it from the 1st
