• 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
