It wouldn't say anything about allocating 'n' addresses in the shared network documentation. Shared network is a concept that groups subnets together. Its only purpose is to tell the DHCP server that all of these subnets exist on the same interface or VLAN or whatever and that a client may use any address or prefix that is in this shared network.

RA are absolutely needed for DHCPv6 to work. Properly working clients won't do anything but sit there with an fe80:: address on its interface if no RA tells it what else to assign and how to do so (https://www.rfc-editor.org/rfc/rfc5175.html) leaving your only option to manually assign address information to the interface on the client. If there is no router, then there will be no upstream routing and you have no need of anything other than an fe80:: as clients on the local network will discover each other and happily talk to each other's fe80:: address. > one more time: address allocation and traffic routing are completely different > tasks that practically do not overlap. at least because there may not be a > router on the network, but ip addresses will still needs In the case of DHCPv6 prefix delegation, DHCPv6 and routing absolutely overlap. Routes must be added to the upstream router telling said router that your client has been allocated such prefix or you won't be routing anywhere as the router will have no idea that said prefix exists on your local network behind your DHCPv6 client. -- ISC funds the development of this software with paid support subscriptions.
