Maybe this will help.

It looks like this is controlled by dhclient(1), though I'm
using a fixed IP, so I haven't tested.  If a DHCP client has
connected to a server and obtained a lease, previously, it
should revert to the old lease (if it hasn't expired) when
it can't reach the server on reboot.

Old leases are maintained in /var/lib/dhclient and in
/var/lib/dhcp.
