If this is an always on machine, it makes no sense, unless the ISP is doing 
agressive accounting on there IP's:
- give out a lease for x hours
- but invalidate it anyway after <x hours.

Doing a periodic dhclient -r would probably fix your problem, though the 
correct solution would be to complain with your ISP and switch to the 
competition if they don't get their stuff together.

Problem with today's modular software: they start with the modules
    and never get to the software part.
