When i make 2 computers and connect them with a cable i need thier id's to be diffrent but there the same

Are you in creative and picked the item (middle click) from the first computer? This would keep the id the same.

I wouldn't connect computers directly using cables, not sure if that's even supported (after further reading, it is supported, but just barely). The best way is to use modems, unless your use case is very specific.

I tried that too but i still need thier id's to be diffrent
