Mission 018

Engineer Briefing

Subnetting is like dividing land.

Basic subnetting creates equal-sized plots.

Example:

A farm divided into:

4 equal fields

But real companies are not equal.

One department may need:

• A large office.
• Another department may need only a small room.

VLSM allows engineers to create subnet sizes based on actual requirements.

Mission Objectives

By the end of this mission, students should understand:

✅ What VLSM is.

✅ Why enterprises use VLSM.

✅ How to calculate subnet sizes.

✅ How to allocate addresses efficiently.

✅ How to design professional IP addressing plans.
