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.
an address that begins with 01-00-5E in hexadecimal
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.
It is a multicast address. If we convert first (it is highest) octet to binary form, we'll see it like this: 00-00-01-11 Because the least bit (last bit from left to right in this line) of the highest octet is set to 1, this address is considered as multicast and is flooded to all points of ethernet network.
