Question: 1 / 1055

How many nodes can be identified by an IPv6 Multicast address?

A single node only

Multiple nodes

The correct choice is indeed the one indicating that an IPv6 Multicast address can identify multiple nodes. In IPv6, multicast is designed specifically to send packets to a group of interested receivers rather than a single destination.

Each IPv6 multicast address maps to a particular group of interfaces, which may span multiple devices across different networks. When a packet is sent to a multicast address, it is delivered to all nodes that are part of that multicast group, allowing for efficient communication to many devices without the need to send a separate packet to each individual node.

It is important to note that while a broadcast address in IPv4 would send packets to all devices on a local network, multicast in IPv6 operates on a group basis, enabling better utilization of bandwidth and reducing unnecessary traffic.
