The Neutron implementation of IPv6 PD doesn't support the use case you're describing, allocating an entire /64 to a device/neutron port.
The Neutron router can only do PD, then advertise the /64 it received on a downstream IPv6 subnet. While this does give the instance an IPv6 address that is globally unique, it's just the single address.
Thanks for your reply and the time to look into this! It might be a bit of a leap, but would this feature not be similar to a floating public IP which I can assign to an instance in the IPv4 world? Certainly with virtually unlimited globally unique IPv6 space there is no need for this in regards to the IPv6 prefixes an instance receives to be reachable - they could all have globally routed and reachable addresses if need be. But some sort of pool of "additional" <s>public</s> globally unique prefixes that can be requested, bound and routed to an instance would be nice - kinda like https://www.terraform.io/docs/providers/openstack/r/compute_floatingip_v2.ht... . What would be the process of getting such a feature into a working specification in case one was interested in implementing this? Regards Christian
