You can't really create anything truly random, since no matter what you do it will always be subject to the life experiences of yourself or whoever you order to "randomize" as well as all of their ancestors and surroundings.

So I don't really see much of a benefit of going computerized randomness over human or "natural" randomness. They're ultimately just a sample from different distributions, which with a computer randomizer you can choose.
Is this why you're trying to do this though? So nobody would know which distribution your address was drawn from?

And even then, mind sharing what the purpose of this whole ordeal is? I don't really see any benefit beyond an academic exercise.
