Windows (an arguable large proportion of the hosts on the Internet) hasn't had IPv6 enabled by default until the release of Vista. Before then it's required obscure cli commands to activate. There doesn't appear to have been much point in doing v6 if a large chunk of your customers couldn't use it. Now they can.
Ah, but now the reverse problem occurs: There's little to absolutely no v6 content. Who's going to want to publish their content on v6, when for the 99.9% of Vista v6 enabled PCs are going to have to reach it via 6to4 or Teredo, over Anycast through Timbuktu? Users are now complaining that your site is slow, and your traffic drops, your revenue goes away, and your v6 experiment fails. ISPs have customers complain that site x, y, z are slow, helldesks recommend that customer does "net ipv6 disable" (or whatever the actual command is). Your v6 traffic goes away, and your experiment fails. It's a chicken and egg scenario and will continue to be so for a long time. I'm very intruiged to know why mobile operators aren't rolling out v6, though - most handsets are dual stack capable, and for all the MMS/WAP crap/etc, there's absolutely no need for v4 address usage. Could it be that no vendors support it?
