No. For something they want.
I cannot request access to a cool new IPv6 site right now. I'm on IPv4. So, my ISP cannot possibly have request for IPv6 traffic from me. Ergo, IPv6 is useless to them (and me).
Have my stacks been upgraded so that my current IPv4 addressing just worked with IPv6, occasionally I would get an AAAA response to my DNS queries (that is also stupid - this should have been simple A - but that's a different issue altogether), which would have a genuine IPv6 address in it. Now, I would not be able to access this site, because my ISP failed to buy IPv6 capable equipment, although my network was already IPv6 ready without me touching a thing in my config (I'm already on the net).
So, I have a choice:
1. Drop this stupid ISP and get one that does IPv6.
2. Tell them they are stupid and ask them to upgrade.
In both cases IPv6 wins by default.
Right now, the onus of IPv6 upgrade is on each and every customer. Each and every customer already connected to the only net we have. For no good purpose whatsoever.
