This is what I was looking for.

I _usually_ have the same IP address assigned by the DHCP server.  Where is 
this "memory" that tries to give me the same IP address?  If it's in the 
server, I'm out of luck.  But if the client tells the server the last IP 
address it held, perhaps this could be exploited.   For example, could I edit 
the fixed-address line in the last lease I held prior to starting up my dhcp
