Excepting temporary failures, they are as far as I am aware. Why do you think they aren’t? > I would think IANA > would have some standard about reachability for root operators. I think you might misunderstand relationships here. The IANA team’s standards are what the community defines. In the case of the root operators, RFC 7720 says “root service” must be available via IPv6 and RSSAC-001 (“Service Expectations of Root Servers”, https://www.icann.org/en/system/files/files/rssac-001-root-service-expectations-04dec15-en.pdf) says: "[E.3.1-B] Individual Root Servers will deliver the service in conformance to IETF standards and requirements as described in RFC 7720 [4] and any other IETF standards-defined Internet Protocol as deemed appropriate." So, in theory, all the root servers should be available via IPv6 and, as far as I can tell, they are. However, the IANA team is not the enforcement arm of the Internet. If a root server operator chooses to not abide by RFC 7720, there is nothing the IANA team can do unilaterally other than make the root server operator aware of the fact. > Until IPv6 becomes provides a way to make money for the ISP, I don't see it > being offered outside of the datacenter. Different markets, different approaches. In the areas I’ve lived in Los Angeles, commodity residential service via AT&T (1 Gbps up/down fiber) and Spectrum (varying speeds) is dual stack by default (as far as I can tell). I suspect all it would take would be one of the providers in your area to offer IPv6 and advertise the fact in their marketing to cause the others to fall into line. Regards, -drc
