224.0.0.10
This address is used for multicast. EIGRP use this IP address.
224.0.0.10
It's a multicast address to be multicast to a group of hosts
The highest usable IP address for non-multicast devices is 223.255.255.254 The highest usable multicast IP address is 239.255.255.254
0100.0ccc.cccd
router#config t router(config)#router eigrp 100 #net NETWORK ADDRESS
The difference is in the IP range. The multicast IP range is 224.0.0.0 - 239.255.255.255

MAC - Media Access Control address comes first, followed by MC - Multicast and then MA - Multicast Address. A MAC address is a unique identifier assigned to network interfaces for communications on the physical network segment. Multicast refers to a communication method in which information is sent from one source to multiple destinations.
In IPv6, the same result can be achieved by sending a packet to the link-local all nodes multicast group at address ff02::1, which is analogous to IPv4 multicast to address 224.0.0.1.
an address that begins with 01-00-5E in hexadecimal
In IPv6, the multicast address subnet ID is 64 bits long. This is part of the overall 128-bit address structure, where the first 8 bits are reserved for the multicast prefix (FF00::/8), followed by 16 bits for flags and scope, and the remaining 64 bits represent the group ID. Thus, the group ID allows for a large number of multicast groups within the IPv6 space.
