And what is wrong with giving every AS an automatic /32? Or to put it in a more systematic manner, let's offer every AS holder some IPv6 space now. Let's ask them to identify how many networks they currently connect in order to estimate the number of /48's that would be used to connect the same number of networks. Then let's round this up to the next highest CIDR block boundary up to a maximum size of /32 and then give them that much IPv6 space, today. The basic principle is that because an AS holder is using IPv4 today, they will almost certainly use IPv6 at some future date. Therefore they have a justified requirement for IPv6 address space. And if an ISP is going to start offering IPv6 services, it is likely that they will eventually be offering those services to all customers. By counting the number of networks/sites they connect today, we have a rough estimate of the number of IPv6 sites that they will connect. But this offer is only a kickstart offer for one IPv6 allocation therefore the offer should be for no more than one /32. This does not mean that the RIRs have to create a swamp. They could reserve a /32 for each AS but only allocate the smaller block. Now, with these assumptions, we have enough information to calulate the amount of IPv6 space that would be used up. Could someone please do the caculations and let us know what percentage of the currently defined unicast IPv6 space would be consumed by such a kickstart program? --Michael Dillon -------------------------------------------------------------------- IETF IPv6 working group mailing list [EMAIL PROTECTED] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
