not sure it is off topic.
I am using a cellular modem to connect to AWS IoT. It works fine for IPV4, now I move to dual stack for IPV4IPV6.
The issue is it appears I only get IPV6 link local address as below and cannot connect to AWS IoT.
May I know if it is normal that my teco just assign IPV6 link local address to my device? It appears OK, but not sure.
BTW, I am using LwIP stack and STM32 Cellular module.
