Please forgive me for being a newbie, but it seems wise to allow subnetting of the lower 64 bits. Afterall, it would be terrible if my dialup ISP assigned a /64 to me, and I had to rely on some IPv6 mythical NAT to do subnetting! A /64 is really quite a lot of address space to subnet; without the ability to subnet, a /64 seems wasteful. In response to the address autoconfiguration using MAC addresses argument, address autoconfiguration can be done using something other than the MAC address in those circumstances. The fact that neighbor solicitations are used to verify the uniqueness of tentative addresses is proof enough that MAC addresses were never meant to be the end all and be all of address autoconfiguration. -jj -------------------------------------------------------------------- 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] --------------------------------------------------------------------
