Hi Khebchi, all 255 is broadcast. That will be the response source and destination, I believe, to a local DISCOVER. If some other behavior is desired, then the traffic must be relayed using a relay agent so that it is no longer broadcast. The relay agent is designed to forward broadcast traffic from a non-local network to a DHCP server as unicast, receive the response as unicast and broadcast that to the local client. See RFC 2131 (https://www.rfc-editor.org/rfc/rfc2131.html) and 2132 (https://www.rfc-editor.org/rfc/rfc2132.html) for (most) details.
