[OT] dhcpd and always-broadcast

[Panayiotis Karabassis <panayk@gmail.com>]

Hey,

I have an OT question about the always-broadcast option of the dhcpd server.

Based on the Wikipedia article, all DHCP messages to the client are sent
to the broadcast address. This makes sense, since the UDP protocol used
by DHCP runs on top of the IP protocol, and the client does not have an
IP address until the DHCP negotiation is completed.

So, what is the use of this option? Under what circumstances should the
server not broadcast its messages?

Thanks, and best regards,
