In computer networking a multicast address is an identifier for a group of hosts that have joined amulticast group. Multicast addressing can be used in the Link Layer （OSI Layer 2）， such as Ethernet Multicast， as well as at the Internet Layer （OSI Layer 3） as IPv4 or IPv6 Multicast. Whichtwo descriptions are correct regarding multicast addressing？（）

A、The first 23 bits of the multicast MAC address are 0x01-00-5E. This is a reserved value thatindicates a multicast application
B、The last 3 bytes （24 bits） of the multicast MAC address are 0x01-00-5E. This is a reservedvalue that indicates a multicast application
C、To calculate the Layer 2 multicast address， the host maps the last 23 bits of the IP address intothe last 24 bits of the MAC address. The high-order bit is set to 0
D、The first 3 bytes （24 bits） of the multicast MAC address are 0x01-00-5E. This is a reservedvalue that indicates a multicast application
