Our ResNets are set at 8 hours but in practice most users keep getting the
same address time after time. (we've taken pains to try and have enough
addresses available for everyone.)

Quick poll for what people are doing with DHCP lease times on their
networks, especially res nets if your network is divided like that and you
have different policies applying to student resident and admin machines.  We
are considering moving to a three month or longer lease time to make it
easier to pinpoint IP usage to specific users/machines.
