I find it slightly ironic that those screaming the loudest for IPv6 seem to have the most poorly researched assertions regarding the death of IPv4. (I am of course ignoring the obvious stupidity of things like IPv8/9/16) Who are the loudest proponents of IPv6? I tend to agree with the evaluation presented in Todd Underwood's blog: vendors, consultants, and the protocol designers themselves... (http://www.renesys.com/blog/2006/03/bashing_ipv6_at_telecomnext.shtml) If IPv6 is the answer, what was the question again? Perhaps it is time to accept that IPv6 is the wrong answer (or we need to start asking better questions), take the lessons learned from its failure, and start again. The past 10+ years of work on IPv6 nee IPng have taught many lessons about what will and will not work (and more importantly what will be accepted or not). There are many fundamental problems with the protocol that no amount of marketecture or hand-waving will fix; the least of which is a lack of end-users calling for a v6 address for their toaster/television/mechanical tie rack. These issue must be addressed, either in IPv6 (not likely), or in IPng-NG :) </soapbox> /joshua ps - the 100-million number likely came from Alain Durand's presentation "Managing 100+ Million IP Addresses" (it says ~20-million customers + kit == 100-million) -- A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools. - Douglas Adams -
