(And towards Marcin: if these policies stop you from assigning /128 to end customers, that was partly the intention. Customers are supposed to receive at least a /64, or better a /56 or /48 - which is why LIRs can get a huge block of addresses quite easily. Don't return into IPv4 "single-address-plus-NAT" land!)
Well, we have never had used NAT, that's not good when you want to be serious ISP. /128 is just an example.
If you give your customers a single /128, you're forcing *them* to use NAT. This is bad.
Probably the simplest way will be subnet /64 or smaller, where part of IP will be MAC address of enduser.
The strong recommendation is to give your customers something between a /48 and a /64. NO LESS, unless you know for sure(!) that they only have a single machine, and no network behind it. IPv6 is not IPv4, and we have enough addresses. Let's make good use out of it. (And the math has been done: giving a /56 to every single end customers out in the world will use up well below 0.0001% of the global address space) Gert Doering -- NetMaster -- did you enable IPv6 on something today...?
