- B.These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
- C.These are like private addresses in IPv4 in that they are not meant to be routed.
- D.These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
- Answer & Explanation
- Report
Answer : [D]

Which of the following is true when describing a multicast address?
- A.Packets addressed to a unicast address are delivered to a single interface.
- B.Packets are delivered to all interfaces identified by the address. This is also called a one-tomany address.
- C.Identifies multiple interfaces and is only delivered to one address. This address can also be called one-to-one-of-many.
- D.These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| Packets addressed to a multicast address are delivered to all interfaces identified by the multicast address, the same as in IPv4. It is also called a one-to-many address. You can always tell a multicast address in IPv6 because multicast addresses always start with FF. |
