I’d check that the script that udhcpc6 runs to configure IPv6 is actually doing something sensible. Especially if you are also trying to use IPv4 as well.
You’ll need a network that is running (IIRC) radv – otherwise you won’t get a prefix length (aka netmask) or any routes. So if IPv6 ‘autoconf’ (SLAAS) won’t give you a valid IPv6 config then neither will dhcpc6.

I learned there is separate dameon (udhcpc6) for IPv6. I need to get an IPv6 address for Cellular network (M2M SIM).
