Pedantic use of terminology is kinda important here. In this case, a name that ends in ".alt" is never part of the global DNS because .alt will not be delegated in the global DNS's root zone. > The Intro says" the rightmost label, to signify that the name is NOT rooted > in the DNS, and that it should NOT be resolved using the DNS protocol. > Isn't that a new root called Alt? It might or might not be, depending on what the non-DNS protocol chooses. This document doesn't tell those protocols what they should do with names that end in .alt. > Maybe it was the part in 4.1 that threw me off. where it says "(and names > ending with the string .alt)" > Or could be 4.1(7) where is says 'to register ".alt" names' Yep, 4.1 is somewhat confusing. > > But this part is super-genius "These > ".alt" names are defined by protocol specification to be > nonexistent" > I had no idea you could specify non-existance. I'm going to have to try that! As Ray points out, if a TLD is not in the root zone, and the root zone is signed with DNSSEC, all names that would end in that (pseudo-) TLD are inherently non-existent to any validating resolver. --Paul Hoffman
