You are to be commended for your leadership in conserving space. Our children will surely be grateful that thanks to your efforts they have 99.99999% of IPv6 space left to work with rather than the paltry 99.9975% that might have been their inheritance were it not for your efforts. Bravo!
Thanks. Actually, I think people are following the RIR example. ARIN handed out a /32 as standard for an ISP, so a /32 is the framework even a medium sized ISP will use. Our routing/IP Numbering Plan: <regional assignment><pop assignment><customer assignment> /40 regional assignment supporting 256 regional assignments /44 for only 16 pop assignments? /48 to customer for only 16 customers per pop assignment? Perhaps another view /40 regional assignment supporting 256 regional assignments /44 still for 16 pop assignments /56 to customer for 4096 customer assignments I'm sorry, but I just couldn't find a way to make /48 to customers work appropriately, and ARIN seems to think a /32 is fair, yet I have to design an IP assignment plan up front to make for more efficient routing. I actually expect a /42-/43 per pop, and /38 per region even in the /56 to customer model. Jack
