Hi Hiihtaja,

I assume we are talking about the echo server sample.

Please refer to my explanation on another case: devzone.nordicsemi.com/.../border-router-using-nrf5340-and-zephyr

Best regards,

Hi Charlie !

So it is not possible to replace fe80 to fd00.

But one interface can have 3 addresses ( or even more ) for example :

fe80::

fd00::

2001:db8::1 global

And via CONFIG lines I can assign only 1 custom address, other addresses assigned automatically or in source code.

Or via CONFIG can assign several ipv6 addresses ?

Regards,

Eugene

Hi Eugene,

I am not sure which sample or library you are working with now.

As OpenThread document mentioned, IPv6 Addressing | OpenThread, different IPv6 address has their own usage scope. You can refer to OpenThread source codes to see how they are assigned and used.

Best regards,

Charlie
