That would be amusing if it wasn't sad. How does a network loop? The reason the for the repeated dhcp requests was implied in my prior message, but I will spell it out: I had two interfaces to which a single IP address was allocated, and the Winbolws machine objected (rightfully).
But to the point: Are you saying that if I have a network configuration error or a device on my network acts incorrectly, then it's OK for services I have running on that system (dnsmasq, in this case) to ignore their configuration parameters and act at will? I hope not, but that is what it sounds like.
