Re: v6 subnet size for DSL & leased line customers

I work on a network with 100K+ DSL folks and 200+ leased line customers, plus some other stuff. The leased line customers are increasing dramatically. I should plan for a /64 for every DSL customer and a /48 for every leased line customer I expect over the next 5-7 years?

why not a /56 by default for both, and give them an opportunity to justify more? a /64 is a bit old-think unless you are having cost issues getting your space from above. randy
