Explanation

Use of well-known UDP ports for client/server communication Both BOOTP and DHCP use the same reserved protocol ports for sending and receiving messages between servers and clients. Both BOOTP and DHCP servers use UDP port 67 to listen for and receive client request messages. BOOTP and DHCP clients typically reserve UDP port 68 for accepting message replies from either a BOOTP server or DHCP server. Because DHCP and BOOTP messages use nearly identical format types and packet structures, and typically use the same well-known service ports, BOOTP or DHCP relay agent programs usually treat BOOTP and DHCP messages as essentially the same message type, without differentiating between them.
