Well, to put it into perspective, imagine that humans would colonize planets around all 400 billion stars in our galaxy (let's say that each star has 10 planets), with 7 billion people on each of them, and each person having 7 billion devices, each device could still have almost 2 million unique addresses available. The range by itself IS big enough for any foreseeable future. The problem may come from the fact that not all that range is available for use.
