Sending UDP messages without IP

[Lucas Robsahm]

Hi!

I'm trying to get a dhcp-server
(http://code.google.com/p/erlang-dhcp-server/) to work but right now I'm
not able to answer on the broadcasted dhcp-discover message that's sent
from IP 0.0.0.0.
When I use a sniffer on the network-devices dhcp-offer message is sent
from 127.0.0.1 to 127.0.0.1, I guess that's the way Erlang or Linux
handle messages to 0.0.0.0.

Is there any way to send UDP messages from Erlang to a computer without
IP-address set?
Is it possible to modify the ARP? I guess that would solve my problem
somehow.
