I.e. even though the "address prefix" command gives you the impression that it will accept /96, this mask is not transmitted to the dhcpv6 client. It's the client which applies the /64 mask. If you're doing subnetting for a big number of sites, you should ask for enough address space for them all. There's plenty of IPv6 address space around - no need to conserve it. In fact, your provider should be able to give you a /48 without any justification at all: that's 2^16 subnets. Are you really operating more than 65k v6 subnets?
