That's impressive to hear. If that is still the case, we will implement and offer an IPv6 DDNS service mid future.
Seriously. If you are blocked for using IPv6 by this, we will provide this service and announce it on https://twitter.com/datacenterlight.

Cheers, I'll keep a look out.
Not sure how common it is for "home ISPs" to issue unstable prefixes, but that's what I got so...
My use-case was exactly what the article highlights, putting my RPi on the net exposing a service.
As I quickly found out DNS was required, as the IPv6 addresses were just impossible to remember. The prefix I got from the ISP was a far cry from the 2001::42 shown in various articles on IPv6.
Then I discovered the prefix wasn't stable across cable modem reboots, and I used autoconfig on the RPi, so the suffix wasn't stable either. So that meant I dynamic DNS was suddenly a required feature, not an optional thing.
After spending half a day trying and failing to find a dynamic DNS service which supported IPv6 and which supported a client I could successfully and reliably use on my RPi, I gave up and went back to plain old IPv4 and NAT.
