Not an IPv6 newbie by any stretch, but we still aren't doing it "at scale" and some of you are, so... For a very small & dense (on 128-bit scales, anyway) network, is RFC3531 still the last word in IPv6 allocation strategies? Right now, we're just approaching it as "pick the next /64 in the range", as it all gets aggregated at the BGP border anyway, and internally if I really try hard, I might get to 200 subnets someday. Is there any justification for the labour in doing something more complex like center-allocation in my situation? Worrying about allocation strategies seems appropriate to me if you have 100,000 subnets, not 100.
