Layer 3 addressing is hierarchical because it allows the division of networks into subnets. For example, one route entry can refer to a large general network and another can refer to a subnet of that same network. When forwarding a packet, the router will select the most specific route that it knows. However, if a specific subnet is not in the routing table but the larger network that holds the subnet is known, then the router will send it to the larger network, trusting that another router will find the subnet.

What is true regarding network layer addressing?
The three correct options are: 3. Hierarchical Explanation: By design, layer three addressing is hierarchical, as you can group hosts in different networks. 4. Uniquely identifies each host Explanation: Each host has a unique address inside its network. 6. Contains a network portion Explanation: For example, in an IP (v4) address a portion of the most significant bits identify the network the host belongs to.1.It supports data communications between networks 2.It prevents broadcasts 3.It uniquely identifies each host
