dhcpd question

[Igor Gueths]

Hi there. Well I just statically assigned an ip to eth1 and configured it
according to the subnet declaration in dhcpd.conf. Isn't there a way tt
the interface's ip from the local dhcp server? I have a friend who has it
set up like this but have no idea what his dhcpd.conf looks like.
