Hi Thomas, I've read yesterday this document, and I'm basically ok with it, but with two considerations that I think must be worked out it parallel somehow: 1) HD-Ratio modification, as it seems to be an integral part of the discussion. 2) I've the feeling that if we suggest the ISPs to move to a /56, they will then charge the customers (SOHO, end-users) or create to them a lot of troubles to get a bigger prefix when this is needed. My feeling is that today we believe that 8 bits for subnetting is enough, but I think will not be the case soon and this barrier will then be again a stopper for enabling innovation. I know this one is somehow not an IETF business, but we must be worried about that and may be collectively work for the appropriate solution in the appropriate fora. Otherwise, I will much prefer not to change the /48 to something smaller. Note that I don't think the RIRs are neither a good fora for making a policy which avoids that the addresses are being charged at all (hopefully I'm wrong !).
The cost of managing addresses is not a recurrent cost. I mean, it will be ok to charge for a reasonable setup fee if somebody ask for a /48 instead of a /56, but charging 12Euros (or even more) per month per address as some telcos do in EU is a crime. We need to make sure that anything like that happens with IPv6 ! Otherwise, we better stop deploying IPv6 now.
