DDNS and ipv6: eth0 not getting WAN ipv6 address.

[unsynaps]

Spotted my syslog spewing the following:

May  3 08:53:45 watchdog: start ddns.
May  3 08:53:45 ddns: eth0 has not yet obtained an WAN IPv6 address.(7)
May  3 08:53:45 ddns: IP address, server and hostname have not changed since the last update.
May  3 08:54:15 watchdog: start ddns.
May  3 08:54:15 ddns: eth0 has not yet obtained an WAN IPv6 address.(6)
May  3 08:54:15 ddns: IP address, server and hostname have not changed since the last update.
May  3 08:54:45 watchdog: start ddns.
May  3 08:54:45 ddns: eth0 has not yet obtained an WAN IPv6 address.(5)
May  3 08:54:45 ddns: IP address, server and hostname have not changed since the last update.
May  3 08:55:15 watchdog: start ddns.
May  3 08:55:15 ddns: eth0 has not yet obtained an WAN IPv6 address.(4)
May  3 08:55:15 ddns: IP address, server and hostname have not changed since the last update.

The thing is, it is my understanding eth0 DOES NOT get a ipv6 address br0 does.
All aspects of ipv6 seem to be working fine best I can tell.

Is something broken here?
