4 D. The minimum IPv6 portable assignment to any organization is to be
an address block of /48. A portable assignment of a block larger
than a /48 can be made if it can be demonstrated that more than
32,768 /64 subnets (or equivalent) are required within its network
or if numbering is required for 2 or more of the organization's
sites operating distinct and unconnected networks.
4 F. An organization must only use portable assignments made under
this policy to address its own networks. An organization must
not use portable assignments to address the networks or sites of
other organizations.
