I suspect the practice of assigning a /48 for every complex layer-3 network isn't scalable for many medium and large service providers. The number of service providers with more than 65536 clients or customers is not just a handful. I would also suggest that many of them aren't even multi-national. The ISP stats at Boardwatch for example suggest the existance of many providers that might find this allocation mechanism to be impractical or wasteful of address space based on the size of their customer base. -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
