Fri 04 Jan 2019 08:08:05 AM UTC, comment #1: I don't think I get it. Where's the bug here? dhcp_release_and_stop() is called to stop the DHCP client and to release the IP address that has been assigned via DHCP. Of course the IP address of the netif has to be cleared there.

After the DHCP successfully acquires an IP address, it will delete it in the mentioned function, so that LwIP is not reachable under the assigned address anymore.
