use large lease times or use fixed addresses

i believe most dhcp clients request the same ip when renewing their
lease, so theoretically you should rarely change address.


(i wrote a simple script once to seed a dhcpd.conf file from an
arpwatch.dat list of MAC addresses. once it was going, it was quite
easy to manually update the fixed-addresses as we added/changed
machines.)
