Detailed explanation-1: -Any MAC address starting with “01:00:5e” is IPv4 multicast MAC address. We have already learned that IP addresses are used in layer 3 (network layer) of TCP/IP protocol stack. MAC addresses are the addresses used in layer 2 (datalink layer) of TCP/IP protocol stack.
Detailed explanation-2: -The multicast MAC address is a special value that begins with 01-00-5E in hexadecimal. The remaining portion of the multicast MAC address is created by converting the lower 23 bits of the IP multicast group address into 6 hexadecimal characters.
Detailed explanation-3: -What type of address is 01-00-5E-0A-00-02? The multicast MAC address is a special value that begins with 01-00-5E in hexadecimal. It allows a source device to send a packet to a group of devices.
Detailed explanation-4: -In Ethernet, different MAC addresses are used for Layer 2 unicast, broadcast, and multicast communications. A unicast MAC address is a unique address that is used when a frame is sent from a single transmitting device to a single destination device.
