Hi Stephen,

Another one has subdivided a /64 into multiple /96's (one for each customer).

Yuck. That doesn't make sense at all.

SLAAC won't work, Privacy Extensions won't work ... you're stuck with static addresses that way, which kills a big part of the ease of management IPv6 could provide, if used properly.

What are they trying to do? Save IPv6 address space? :-)

It's a server farm based on Xen instances; they assign a single static address from one /64 and then route a /96 from a second /64 to that address. Since it's a server farm they, presumably, don't care about privacy extensions nor SLAAC and expect static addresses.
