We are going thru a similar process.. from all of my reading, best practice discussions etc.. Here is what i have understood so far:- Residential Customers: /64 Small & Medium size Business Customers: /56 Large Business size or a multi-location Business Customer: /48 Don't skimp on allocating the subnets like we do on IPv4 Better to be 'wasteful' than have to come back to re-number or re-allocate .

I am planning out our IPv6 deployment right now and I am trying to figure out our default allocation for customer LAN blocks. So what is everyone giving for a default LAN allocation for IPv6 Customers. I guess the idea of handing a customer /56 (256 /64s) or a /48 (65,536 /64s) just makes me cringe at the waste. Especially when you know 90% of customers will never have more than 2 or 3 subnets. As I see it the customer can always ask for more IPv6 Space.
/64 /60 /56 /48
Small Customer? Medium Customer? Large Customer?
Thanks
Erik
