Stop cringing and give them /48s. It’s really not going to harm anything. Really. Look at the math. That scale of waste is a very very pale glimmer compared to the LAN side of things where you have 18,000,000,000,000,000,000 (and then some) addresses left over after you put a few hundred thousand hosts on the segment. Also, claiming that 90% will never have more than 2 or 3 subnets simply displays a complete lack of imagination. Household networks will continue to gain sophistication and with automated topologies developed through more advanced applications of DHCP-PD, you will, in fact, start seeing things like WLAN+GuestWLAN+LAN on separate segments, entertainment systems which generate their own segment(s), appliance networks which have separate routed segments, etc. Unfortunately, most of these future applications don’t stand a chance while we’re still mired in IPv4 and IPv4-think about how to allocate addresses.

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
