What's happening here is that the client is in the RENEWING state, not
the REBINDING state, so if its DHCPREQUEST doesn't get a response, it
blissfully keeps using the old address until it gets to the REBINDING
state, at which point it will eventually broadcast a DHCPDISCOVER and
probably be dealt with correctly.

The next question is, why isn't it getting the DHCPNAK?  I'm not sure
- I don't have enough information.  Is this client connected to a
network to which the DHCP server is also connected?  Can you send me a
complete log of what the server prints out when you start it and when
you move the client from one net to the other?  (The dhcp-v4 list
probably doesn't need to see this.)
