Interesting idea, however I am not conviced that a hierarchic model is desirable to guarantee uniqueness (I do understand the appeal, don't get me wrong). What concerns me is the fact that if you take delegation far enough you will end up with a very limited set of "N"-s per domain, and thus the ability to track users. Furthermore, I think the requirements for unique identifiers are not the same as for domain names. Arguably the delegation of subdomains is meant as a way to indicate some sort of subordinate relation, i.e. sales.acme.com is the sales department of acme etc. For uniqueness of identifiers I see no clear reason why you need a hierarchy, other than to avoid collissions. Don't you think it much easier to just use a method with a very low probability of collissions and deal with those?

A universally unique identifier is needed to let nodes roam everywhere in the common network while preserving their ongoing communication sessions. To keep identifier unique a system for issuing, distribution and control over it is needed. The system has to provide uniqueness and also be flexible and robust. There is an acting solution with much the said characteristics. That is the DNS with its FQDN. The FQDN is by best effort universally unique. And the DNS has proven itself to be surviving and moreover prevailing. Because of node mobility the Dynamic DNS is the closer match. With this technology a node can change its topological location and retain a same identifier. But the FQDN is not quite suitable for the hereby projected usage. It is made out of names that are for human use. This not a networking best practice. So, can we turn the top supported network node identifier system into a useful solution for also session identification supplement? And how? Yes. By deciphering the N as "number". That's all to it. A dynamic domain number system can supply the desired network node identifier. The fully qualified domain number will be hierarchically structured, fairly distributed, unique.
