• Neutron support for delegation of prefixes to subnets

• Feature enabled by an option in neutron.conf

• When enabled, the user no longer has to provide a CIDR when creating an IPv6 subnet

• Admin does not need to configure a default IPv6 subnetpool

• Requires a PD-capable DHCPv6 server

• Server is responsible for uniqueness of prefixes, and routing of traffic
