    _______________________________________________________

Details:

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.

The line in question is this:

After commenting out (removing) this line, the tested HTTP server works as
expected.
