Follow-up Comment #1, patch #8692 (project lwip):
There is an other option, PPP could also switch back to
DNS_SERVER_ADDRESS, I'll let Simon decide :)
Indeed returning straight off if no DNS server is configured looks like
better from an overall design point of view, but who cares if uplink is
currently down ? It might also help apps which are not designed with an
holdoff between tries which will then loop as fast as possible on DNS
request.
