I though it was explicit with IPv6 that end-nodes are not-host identifyers. In the real world today, IPv6 addresses are certantly not host-identifyers: Many hosts (including the one I'm typing on) have multiple IP addresses, and sites have a farm of web serverers behind a single IP address. We may pretend that a IP address means a host, but it doesn't.
