I can see a distinction here between "names that are currently in the public root zone", and "names that might someday be in the public root zone". Obviously, the former is a finite list of names in operation, and can serve as a reference to avoid name conflicts with non-DNS namespaces: they already exist, so they should be considered solid. Besides, if I understood well, there's a procedure to send decommissioned domains to a 50-year-purgatory before they return to the "unused" set. On the other hand, this latter set of unused, potential domain names is the complementary of the former in the superset of all domain names: making it special as such would determine the future of the namespace, which seems to go against the idea of letting reality unfold and adapt to it. So I'd recommend a clear distinction is made between "existing domain names in the public root", and the rest of the set, kept as undetermined and irrelevant to daily operations. > Our current > approach as documented in RFC 6761 comes at this question from the > perspective that the IETF can declare whatever names it likes to be > so "protected" by extending the standard with a new entry in the > special use names registry, but takes no account of any possible > distinctions between names currently in use at an arbitrary time > for the DNS, names that will (or even might) be in use at a future > time for the DNS, and any other categories. > I'm not sure I understand what you mean by "currently in use at an arbitrary time for the DNS": it sounds to me as an equivalent to "the superset of all possible domain names" that I evoked earlier; if a domain is in use now, it's part of the set of "existing domain names in the public root", otherwise it's undetermined. Or do you mean there should be a preemptive complete assignation of the domain namespace? I don't think it's possible to predict an ordered way of revealing the namespace until its exhaustion: it sounds mechanistic. Maybe you're suggesting that some names should be reserved for future use? In that case I fear arbitrariness may be the rule.
