I am with Ilji. A well-organized hierarchical system can easily guarantee global
uniqueness. Every level can control it only assigns unique prefix to next level
within its only prefix pool. Both FQHN and IP address are good examples, which have
achieve global uniqueness. It is only difficult if we want to achieve global
uniqueness with pure flat structure, like current HIT. Now, the point is whether
statistical uniqueness is enough. If the answer is no, change the structure.
