/64 is the smallest available subnet by design and many things will break the moment you try to subdivide further. The idea was that the lower 64 bits would identify a particular NIC by it's MAC address; this was later changed to be a randomized suffix. This is why most machines typically have hundreds of v6 addresses - they generate a new one every few hours.
