The file /etc/default/dhcp3-server contains the reference to the interface where the service needs to listen to.

# Defaults for dhcp initscript
# sourced by /etc/init.d/dhcp
# installed at /etc/default/dhcp3-server by the maintainer scripts

#
# This is a POSIX shell fragment
#

# On what interfaces should the DHCP server (dhcpd) serve DHCP requests?
#       Separate multiple interfaces with spaces, e.g. "eth0 eth1".
INTERFACES="eth0"

The file /etc/dhcp3/dhcpd.conf is the configuration file of the server.
