I think they did in fact mean IPv6-only hosts. For instance, you can save some money getting a virtual box on Hetzner that doesn't have IPv4 connectivity. Of course, that box won't be able to talk to ex. github, so for some people it's really not worth it.

GitHub.com not being available over IPv6 is the most harmful thing for IPv6 penetration.

		That and poor support from cloud vendors. Looking at you, Azure. How is IPv6 not enabled for everything by default? It boggles the mind.
