N = the number of subnets you have in IPv4. N * /64 = the bare minimum amount of IPv6 space you need. If you are an ISP, then, it becomes a bit more complicated. N = the number of customers you have that have a single subnet O = the number of customers you have that are SO/HO or small business and can get by with a /56 and do not request more. P = the rest of your IP transit customers. (N+256(O)+65536(P)) * /64 = the bare minimum amount of IPv6 space you need for customers. You must, then, add a /64 for each of your own infrastructure networks as well. > ARIN does provide microallocations, but ICANN forced them to put "for ICANN > approved > root service only" into their policy for microallocations, so that leaves us > out. > ICANN can't force anything into ARIN policy. If you want that wording changed in ARIN policy, you can submit a policy proposal. If it gains community consensus, the wording will change and ICANN/IANA will have to live with that. IANA policies are set through a bottom up process that comes from the RIRs, not the other way around.
