James,
If I remember correctly, you mentioned a bit ago that your job required
you had native IPv6 at home.
Question: Does an ISP providing you IPv6 out of the CPE box (meaning,
without any software other than dual-stack on the hosts) qualify as
native IPv6 if, behind the scenes, they use a tunnel broker, or 6rd?
Facts are AFAIK that:
- Tunnel brokers need host cooperation. They can't be used behind the scene
by ISP's.
- 6rd can indeed be used behind the scene by ISP's, without users making the
difference with native IPv6 routing in ISP networks. This has been proven on
a large scale over 3.5 years.
I would suspect that there's nothing that prevents an isp running it's own
tunnel broker and a compliant cpe from automating that process in much the same
way that 6rd in free required control over the firmware. the business case for
doing so seems like an exercise for the reader.
Regards,
RD
