Random unique number like IP address mysql

Question

I'm making an android game which is made with a hacking theme, and I want to generate a random and unique IP address-style user ID (example xxx.xxx.xx.xx)

At the moment I know how to generate a unique ID, but it is just incremented from 1 and up.

I don't know if it is maybe only possible through php? Or even the android app's side?

Any help would be greatly appreciated!

Try this on Android app side,

Random random = new Random();
return random.nextInt(256) + "." + random.nextInt(256) + "." + random.nextInt(256) + "." + random.nextInt(256);

See this SO thread.

Edit : To generate random numbers without repeatations, see this thread. You will have to modify it for your need though.

Thanks, but I also want to make it unique, because I think this might generate two of the same numbers (the chances are **VERY** slim but still possible). Any idea on that? – Johan De waal Nov 15 '16 at 16:48
I will try this as soon as I get back on my PC! Thanks so far! – Johan De waal Nov 15 '16 at 17:10
