Engineer Briefing

Imagine a city.

Inside one building, people can find each other easily.

They know:

• The rooms.
• The people.
• The local layout.

But what happens when someone needs to send a package to another city?

The local room number is not enough.

They need:

• A city.
• A street.
• A destination system.

Networks work the same way.

Inside a LAN:

We use MAC addresses.

Between networks:

We use IP addresses.
