Interesting question.
Someone smarter than I will come up with the real reason. But my guess is
that the requester can't send a unicast because it does not know the mac
address in the first place. If it did, it wouldn't have to make the request.
:->
Recall that to place the packet on the wire, the sender must place a mac
destination address in the layer two header. The arp request goes to mac
address ffff.ffff.ffff ( mac broadcast )
Makes sense to me. Just waiting for the corrections to come.

Hi All,
Could any one explain why ARP needs to broadcast when looking for the MAC
address. Why not send a unicast using the given IP address.
Regards to all
