Theoretically, it could do it during the discover and offer stages, but
not during the request and ack stages, since the first two use broadcast
while the second two use the siaddr to directly send the packets.

if it doesn't have a range to use in the offer. You could try it
without a range, possibly as a shared-network with a pool statement with
no ranges. Again, I have never tried, but I don't think it will work
without at least something that dhcp can send as the IP. Perhaps
0.0.0.0/0 as the offered IP?
