Gert-

Yes, I understand it's 256 hosts when you are assigning a /64 per node. But as the specific draft references:

"   *  In small networks (e.g., home networks), where the number of
      clients is not too high, the number of available prefixes becomes
      a limiting factor.  If every phone or laptop in a home network
      were to request a unique prefix suitable for SLAAC, the home
      network might run out of prefixes, if the prefix allocated to the
      CPE by its ISP is too small (e.g., if an ISP delegates a /60, it
      would only be able to delegate 15 /64 prefixes to clients).  So
      while the enterprise network administrator might want all phones
      in the network to request a prefix, it would be highly undesirable
      for the same phone to request a prefix when connecting to a home
      network."

However, I will say I agree that this one single use case could have potential issues if these 2 things are true:
1. DHCPv6-PD is enforced for all nodes
2. the network's allocation is only a /56 or /60

However, if that were the case it would only affect a specific situation. And is this even the intent behind this draft from the authors Lorenzo, Jen, and Xiao?

Hi,

Please read up on 

https://datatracker.ietf.org/doc/draft-ietf-v6ops-dhcp-pd-per-device/

.. that's the point here.
