IPv6 deployment is in a chicken and egg situation. On the one hand, there is no willingness from ISPs and commodity DNS router manufacturers to include IPv6 support in their infrastructure or equipment because “there is no demand”. On the other hand, there is no demand because the average Joe Blow could not care less if he accesses a web site under IPv4 or IPv6. It should just work. The equipment and infrastructure should adapt transparently… What we users can do is to stop waiting for the industry to get its act together and work around its limitations.
