Further to my previous question, I can see that the dnsmasq _was_
listening in  127.0.0.1, 172.17.0.1 and 10.3.1.79, and then it attempts
to listen on  127.0.0.1, 172.17.0.1 and 10.3.4.228, so that implies a
network configuration change, with something changing 10.3.1.79 ->
10.3.4.228. Any idea what that's about? If you can find what causes that
change, we might, at very least, have a way to reproduce this at will.
