That's trivial - just compare to the list of IP addresses configured  
on each interface.   But why do you care in that case?   The only  
case where you really need to know to what interface a client is  
connected is the case where it's broadcasting.   When it's in the  
RENEWING state, you don't have enough information to send a DHCPNAK  
with any degree of reliability anyway.
