 I think nosy needs some sleep because she hasn't slept last night.

I dont see any problem there.

Do you?

...
  So record is missing at dns. If dns cannot be changed
ipv6 address must be 
 added to /etc/inet/ipnodes (which is always a good idea if dns is not 100% 
 reliable). /usr/lib/inet/in.ndpd is running.

...
  ifconfig -a6 shows that the ip address is configured
three times as local 
 interface for the same physical interface. Is this expected? And physical 
 interface bnx0 is associated with a link local address only. This shows that 
 the router is not propagating the site prefix. So you must change the router 
 config or add the site prefix locally. Maybe interfaces were not plumbed.

I'd really like to reboot tomorrow. Everytime I do what is the equivalent to 
/etc/init.d/networking restart it adds an interface with the v6 address.

The next try from my side would be to switch back to the old v6 range to see if 
the problems all go away. I currently cant reach even from the same network.

root@willow:~# ping 2a02:ec80:101:301::2:2

^C

Solaris is not my home base system but I only changed the prefixes in the 
config files so it should work as it did before.

Lets see how this goes tomorrow after some sleep.
