Subnetting Network Topologies

Overview

Goals

The goal of this exercise is for students to learn and understand how the subnetting of a network topology works and how they can subnet a network by their selves. Students will subnet the network address and provide an IP addressing scheme that will accommodate the number of subnets displayed in the topology diagram, giving them a general idea on how IP addresses are contributed throughout device interfaces.

Learning Objectives

After this exercise, students will be able to: • Determine the number of subnets • Design an appropriate addressing scheme • Assign addresses and subnet mask pairs to device interfaces • Examine the use of the available network address space and future growth potential

Context

When given a network topology, it is important to be able to determine the number of subnets required. In this lab, several scenario topologies will be provided, along with a base network address and mask. Students will subnet the network address and provide an IP addressing scheme that will accommodate the number of subnets displayed in the topology diagram. They must determine the number of bits to borrow, the number of hosts per subnet, and potential for growth as specified by the instructions.
