      I'm talking about dynamic leases here.  I have customers that will 
get a different IP when they update their systems because their UID will 
change.  If the leases were based on their MAC instead, then their IP 
would remain the same.

      So the question still remains:  How to have dynamic leases based 
on MAC addresses?


Any takers?
