(I would _almost_ agree that "pet" should never be looked up as plain "pet" - except that I think it should be possible to directly query a server to find out what RRs that server has (right or wrong) and I wouldn't want the server to lie or the API to prevent such queries. That's why I would rather forbid servers to forward single-label queries - and perhaps, to refuse to cache NS records for them.) > If I "want" those labels to work at all it's because their working > reflects a clean DNS design. Cleanliness is secondary to function. The purist in me likes regularity too. But even if the _protocol_ is the same at the root as for any other zone, the root of the _name space_ really is special, and inherently so (given that these labels have semantics associated with them). At a certain very technical level there is no difference between the root and any other zone. But at a different level the root has a special role and is different than the other zones. It is a single point of failure - not in the sense of a single server or a single network link but in the sense of a single organization running it whose mistakes affect the entire network. Also, the relationship between the root and its subdomains is likely to be very different than that between any other domain and its subdomains. > If you're worried about a flat namespace, attack the right problem - a > proliferation of TLDs, not this business of the TLD having an A record > at the top. Vanity TLDs are indeed part of the problem. Without vanity TLDs there would be much less incentive to have single-label domain names. (I guess I need a better name than "vanity" TLDs for these - but I think you get what I mean.)
