If you turn on IPv6 +50% of your traffic will shift to IPv6 immediately<br>
for every customer that has a IPv6 capable CPE device. This is<br>
*not* IPv6 going nowhere.<br>
<br>
The content providers are going IPv6-only internally translating<br>
IPv4 to IPv6.<br>
<br>
If you ship CPE router make sure they are IPv6 capable.<br>
<br>
If you do not ship CPE routers provide a list of IPv6 capable routers<br>
you are happy with. IPv6 routers can be got for < $100 AUD.<br>
