You may have noticed that the dhcp request that phil-f¢s imac sends is a broadcast packet, sent to ethernet address: ff: ff: ff: ff: ff: ff, and ip address: 255.255.255.255. but when his imac sends the dhcp request it has already selected an ip address and it knows which server the selected offer came from. why does it send the request as a broadcast packet? a. this way all dhcp servers on the network will get a copy of it, so they can withdraw other offers that were not selected. b. all dhcp servers must get a copy of the request so they can update their mappingsc. dhcp is a distributed protocol and the broadcast packets ensures that servers are synchronizedd. there is a mistake in the implementation; the dhcp request should be a unicast packet.
