OBJECTIVES

At the end of the lesson, students must be able to:

1. define IP address and explain its purpose in networking,

2. differentiate between static IP and dynamic IP (DHCP), and

3. Understand where static IP configuration is typically used.

📘 What is an IP Address?

An IP Address (Internet Protocol Address) is a unique number assigned to every device connected to a network.�It allows computers and devices to identify each other and communicate within a local or internet-based network.

📌 Example format: 192.168.1.10 (IPv4)

It’s like a “home address” for your computer in the digital world — without it, devices wouldn’t know where to send or receive data.

🧠 Common Usage Scenarios for Static IP

Devices that need to be accessed regularly or remotely work best with a static IP, because it’s reliable and predictable.

Examples:

📷 CCTV security cameras — need fixed IPs to be monitored 24/7

🖨️ Network printers — to avoid “printer not found” issues

🌐 Web servers — for stable hosting and access

🖥️ File servers and NAS (Network Attached Storage) — for storing and accessing files in offices

What happens if two devices have the same IP?
Why might we prefer static IP in a school or office?

To configure your server with a Static IP address, follow these steps:�

5 Click the Use the following IP address selection button, and then enter the following information in the appropriate textboxes.

CCC recommends using a non-routable

address range such as the following:

Workstation 1: 192.168.0.10

Workstation 2: 192.168.0.20

Subnet Mask: 255.255.255.0

Important! Each system on the network must be configured with a unique IPaddress.

Assignment

Title: "Where IPs Live"�Interview someone at home (e.g., a techie, gamer, or parent) and ask:

Do you know what an IP address is?
Where do you see it on your device?
Do you know if it’s static or dynamic?
