Hi, I am not sure you got that right.
If you are an ISP the minimum assignment is /32 and you assigned /48 to end company and /56 to users. If you asked me that's a wasted, but that's what they suggest. For end users, a /64 would be plenty if you asked me and /56 for company would be plenty as well. But if you truly follow their policy, then well may be will run out there too like in IPv4 when it really start to be assigned, but anyway that's for a different discussion. Anyway see ARIN policy for it: https://www.arin.net/vault/policy/archive/ipv6_policy.html If you are not under ARIN, but RIPE, APNIC, AfriNIC, Lacnic, etc. They have similar policy. I would encourage you to check that if your problem is really that you got to small assignment. Unless your a very small ISP that got his assignment from your transit provider oppose to your own and get your own AS number, you will have plenty to work with. I really do not know of ANY ISP that get /56 for real. I got my assignment in 2003 and the policy still haven't changed. Hope this help you some. Daniel.
