Do you mean that lwIP's DHCP client never times out then?

What tool is this? Is that perhaps some kind of small DHCP server?

My current approach has been working very well: If a user removes the device 
from the network and connects it to a local laptop for reconfiguration 
purposes, after a few seconds he can access the device at the fall-back IP 
address. No external tools are necessary. And there is no need to reset the 
device IP configuration with any external button. Just reconnect it to the main 
network, and it works again as usual.

I think I have seen other devices with DHCP but with a fall-back IP address too.

That is good news. Thanks!
