As the Hierarchial IP addressing as the three parts for routing the IP addresses, where 192.168.17.2 as the three parts. 192.168.x.x comes under network part, and remaining parts are divided into subnet and host parts.

I need a non-network example of hierarchical addressing, and discuss how it reduces the amount of work needed in physical delivery. Do not use any example as the postal service, or the telephone network.

Need good explanation for the presented example...... how the hierarchy addressing works in the example.
