A client that sends out a DHCP Discover message in order to receive an IP address sends out a broadcast at both layer 2 and layer 3. The layer 2 broadcast is all Fs in hex, orFF:FF:FF:FF:FF:FF
. The layer 3 broadcast is FF:FF:FF:FF:FF:FF
, which means all networks and all hosts. DHCP is connectionless, which means it uses User Datagram Protocol (UDP) at the Transport layer, also called the Host-to-Host layer. Related Questions on TCP IP
