Hi Paul,

I have found it in this link
- https://github.com/zephyrproject-rtos/zephyr/issues/10561 By
referring the config file also we can able to find Echo client and
server example can be built for either OpenThread or third party IP
stack.
https://github.com/zephyrproject-rtos/zephyr/blob/master/samples/net/echo_client/overlay-ot.conf
Remaining config files will be used to build for other configurations
- https://github.com/zephyrproject-rtos/zephyr/blob/master/samples/net/echo_client/

None of the links you mention has occurrence of "lwip" (case
insensitive) in any material it points to.

Zephyr doesn't work with lwIP, it has own IP stack. However, I'd be
interesting to hear if someone integrated lwIP with Zephyr
(apparently, bypassing its native IP stack), so if you have any links
substantiating that, please feel free to share them.

Thanks & Regards,
Deepa
