The temporary visitor in the cube next to mine keeps getting my preferred IP.  
Yesterday evening we confirmed he had the IP, and I could also ping the IP.  
This morning, I got in early, before he arrived and plugged his laptop into 
our network.  At the time I could not ping the IP, nor could I get the IP 
from the DHCP server.  After he arrived and plugged in his laptop, he got my 
preferred IP back again, and I can ping it again.

Could the server hold an active lease on this IP while the laptop has been 
removed from the network?
