https://tools.ietf.org/html/draft-diao-aip-dns Each ISP - large enough to obtain a TLD from IANA for this purpose - should be allowed to create it's own DNS hierachy. This Chinese proposal is justified by the fact that the (U.S.) centrally managed name space represents a risk for the stable operation of the Internet. Following this draft different name spaces are spanned, each of them operated autonomously. Which domain names are allowed, added, or removed; how a domain name is resolved, is soley in the hand of the operators. Using the typical definition, that "the Internet is the transitive closure of all systems communicating bidirectional via Internet Protocol, which contains the DNS root servers", the Internet is splitted by this proposal. There is no reason to believe the rumours, that this proposal is a direct consequence of the ICANN desaster with new gTLDs. On the other hand, DNSSEC root keys at the end user systems define which root have to be used in the first place. This can be used to establish and protect the new name spaces.
