Re: IPv6 Default Allocation - What size allocation are you giving out

There seem to be lots of various opinions still on this subject.

What type of customer are you dealing with, what service are they receiving?

We are allocating a /64 per customer (VPS / dedicated server / small co-lo)
but doing them on /56 boundaries so that we can easily expand their
allocation if needed, as well as back-fill more /64 allocations in that
address space.

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
