Which three components make up an IPv6 global unicast address?

An IPv6 global unicast address comprises three distinct components that play crucial roles in the addressing scheme. The first component, the global routing prefix, identifies the network portion of the address and is assigned by the Internet Assigned Numbers Authority (IANA) to organizations for their use. This prefix enables routing on the global Internet, directing packets towards the correct destination network.

The second component is the subnet ID, which helps identify a specific subnet within the global routing prefix. This is especially important for organizations that divide their allocated address space into smaller subnets for better management and improved efficiency in routing.

The final component is the interface ID, which uniquely identifies an interface on a device within a specific subnet. This allows for packet delivery to the correct device on the network. Together, these three components allow for unique identification of devices within a broader network configuration, facilitating efficient routing and communication.

In contrast, the other options include elements that do not align with the structure of an IPv6 global unicast address. For instance, they reference IPv4 addressing concepts or other components that do not belong to the standard IPv6 addressing scheme.
