Helllo,



I am trying to get a public ipv6 ip addres but I am failing. I know that my service provider uses prefix delegation for assingning public ipv6 to ipv6 hosts. My windows machines are getting public ipv6 as normally. But my raspbian machine is not getting public ipv6, it only creates FE80:: link local adresss. When I checked syslog, I can see that ipv6 assingnements are constantly flapping between public ipv6 and linklocal ipv6 as you can see below:



Could you please help me with that? Why router advertisements are expiring so soon? And How I can get public ipv6 address?
