ADDRESSING PLAN

📌 IP ADDRESSING PLAN WITH SUBNETTING FOR OFFTUBE 🌐

1️⃣ Objective 🎯
The main goal is to design a segmented network to ensure efficient, secure, and scalable management.

We will divide the network into three main segments:
✅ Client network (Users) – For laptops.
✅ Server network (Servers) – For virtual machines and company services.
✅ Administration network (Admin) – For system management.

Each segment will have a specific subnet to avoid collisions and improve performance and security.

2️⃣ Network Overview 🔄

3️⃣ Device Assignment per Network 🖥️📲

📌 Client Network (192.168.1.0/26)
👉 For user laptops and general-use devices.
👉 Supports up to 62 devices.
👉 Example IPs:

• 192.168.1.1 – 192.168.1.30 → User laptops

• 192.168.1.31 – 192.168.1.62 → Office equipment

📌 Server Network (192.168.1.64/27)
👉 For physical and virtual company servers.
👉 Supports up to 30 devices.
👉 Example IPs:

• 192.168.1.65 → Web server

• 192.168.1.66 → Database server

• 192.168.1.67 – 192.168.1.94 → Virtual machines

📌 Administration Network (192.168.1.96/27)
👉 For admin and control devices.
👉 Supports up to 30 devices.
👉 Example IPs:

• 192.168.1.97 → Admin router

• 192.168.1.98 → Main switch

• 192.168.1.99 – 192.168.1.126 → Admin consoles

📌 Reserved Expansion (192.168.1.128/25)
👉 For future network scaling.

4️⃣ Subnetting Justification & Benefits 📈

✅ Security through segmentation 🔐
Each network is isolated, preventing unauthorized access.
Clients can’t access servers directly.

✅ Optimized IP usage 🚀
Subnetting fits the IP count to real needs, avoiding waste.

✅ Easier management 🖥️
Each network has a clear function and structured IPs.

✅ Future scalability 📊
The 192.168.1.128/25 space allows for expansion without major reconfiguration.

5️⃣ Device Configuration 🛠️

📍 Router and Switch

• Assign static IPs to servers and admin equipment.

• Configure VLANs for each segment (VLAN 10 – Clients, VLAN 20 – Servers, VLAN 30 – Admin).

📍 Firewall & Security

• Filtering rules to block unauthorized inter-network access.

• Allow only essential ports and protocols between segments.

📍 DHCP

• Automatic IPs for client network devices.

• Manual IPs for servers and admin equipment.

6️⃣ Conclusion 📌

With this well-structured addressing plan, Offtube’s network will be secure, efficient, and scalable. Subnetting enables clear segmentation of devices, boosting performance and safety.

🔹 Clients connect without interfering with servers
🔹 Admin network is protected and accessible only to the technical team
🔹 Room for future expansions with no major disruptions
