1- Reduces routing table entries
2- Ease of management and troubleshooting.
An example is IPv4 addresses having network, subnetwork, and host portions.
A hierarchical network
distribution
If a network uses static addressing, it means that each network interface has an assigned IP address that it uses all of the time or whenever it is online. If a network uses dynamic addressing, it means that when a network interface asks to join the network, it is randomly allocated an IP address from a pool of available addresses within that network. Thus, under dynamic addressing, a computer may possess over time (e.g. across reboots) a variety of different IP addresses, but under static addressing the computer has a well-defined IP address which it uses always and which no other computer ever uses. Dynamic addressing is most useful in applications such as dial-up networks, VPNs, and similar scenarios where end-user machines are intermittently connected to the network.
interconnected networks is the basic meaning of internet... it resembles a hierarchical network form...
The use of network prefixes in IP addressing enables it to be hierarchical. By subdividing the address space into network and host portions, IP addresses can be aggregated into larger blocks that simplify routing and management of networks. This hierarchical structure allows for efficient routing of data packets across a network.

Reduced content for bandwidth Increased fault tolerance of the network Simplification of management and troubleshooting
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.
Network Address
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
In network model of database , all data is related to each other through a link. By a link we mean that it is an association between precisely two records/data . In hierarchical model records are organized as trees rather than arbitrary graphs.
A network structure is more a star topology whereas a Hierarchical structure is like a tress... Allowing you to drill down to get to an answer.
The hierarchical data model organizes data in a tree-like structure with a single parent for each child record. On the other hand, the network data model allows for multiple parent-child relationships, creating a more flexible and complex network of interconnected records. In the hierarchical model, relationships are one-to-many, while in the network model, relationships can be many-to-many.
