[address-policy-wg] 2006-02 Last Call for Comments (IPv6 Address Allocation and Assignment Policy)

Are you assuming that organizations never subnet inside a building ?

In IPv6 if you want to keep things working, the minimum network is /64, so
if somebody want to subnet, you need to give them something bigger, and
current IETF recommendations are still /48, as per RFC3177.
