Top Programming Languages to Know in Network Engineering

Modern network engineering is no longer just CLI commands and cable tracing. Automation, cloud networking, and infrastructure at scale have made programming a valuable skill.

Here are some of the most useful languages for network engineers:

1️⃣ Python – The king of network automation. Used for configuration management, monitoring, API integrations, and troubleshooting.

2️⃣ Bash – Essential for working with Linux-based network devices, servers, and automation workflows.

3️⃣ PowerShell – A must-have for Windows environments, Active Directory management, and network administration.

4️⃣ Go (Golang) – Fast, efficient, and increasingly used for cloud networking tools and network services.

5️⃣ JavaScript – Useful for network dashboards, web interfaces, and API-driven network applications.

6️⃣ SQL – Helps when working with network monitoring platforms, logging systems, and large datasets.

7️⃣ YAML – Not technically a programming language, but widely used in network automation tools like Ansible.

8️⃣ JSON – The language of APIs. Understanding JSON is crucial when interacting with modern network devices and cloud platforms.

9️⃣ C – Helps you understand how networking works under the hood, including sockets, protocols, and operating systems.

🔟 Rust – Growing in popularity for building high-performance and secure networking applications.

The reality is that if you learn Python, Bash, PowerShell, and basic JSON/YAML, you're already ahead of most network engineers.

Which one are you learning first?

NETWORKING FUNDAMENTALS

[𝐇𝐚𝐦𝐳𝐚 | Network Engineer (Aspiring) @Hamzaonchain]

The OSI (Open Systems Interconnection) Model is a framework that explains how data travels between devices on a network. It consists of 7 layers, each responsible for a specific part of the communication process.

1. Physical Layer

What it does:
Handles the physical transmission of data as electrical, radio, or light signals. This layer deals with cables, connectors, and network hardware.

Examples: Ethernet cables, Wi-Fi signals, USB, fiber optics.

Analogy: The roads that vehicles (data) travel on.

2. Data Link Layer

What it does:
Packages data into frames and ensures reliable communication between devices on the same network. It uses MAC addresses to identify devices and helps detect transmission errors.

Examples: Switches, MAC addresses, Wi-Fi (IEEE 802.11).

Analogy: Traffic rules that help prevent accidents and keep vehicles moving smoothly.

3. Network Layer

What it does:
Determines the best path for data to reach its destination across multiple networks. This layer uses IP addresses and routing protocols.

Examples: Routers, IPv4, IPv6.

Analogy: A GPS system that calculates the best route to your destination.

4. Transport Layer

What it does:
Ensures data is delivered correctly and in the proper order. It breaks data into smaller segments and reassembles them at the destination.

Examples: TCP, UDP, port numbers (e.g., HTTP uses port 80).

Analogy: A delivery service that packages, tracks, and confirms shipments.

5. Session Layer

What it does:
Establishes, manages, and terminates communication sessions between devices.

Examples: Video conferencing sessions, user login sessions.

Analogy: A phone call—connecting, maintaining the conversation, and ending the call.

6. Presentation Layer

What it does:
Translates, formats, compresses, and encrypts data so it can be understood by the receiving application.

Examples: JPEG, PNG, SSL/TLS encryption.

Analogy: A translator ensuring both parties understand the same language.

7. Application Layer

What it does:
Provides network services directly to end-user applications and enables users to interact with the network.

Examples: HTTP, SMTP, FTP, DNS, web browsers, email clients.

Analogy: The apps on your phone or computer that let you browse the web, send emails, or transfer files.

IPv4 Addressing Made Simple 🌐

Every device on a network needs an IP address think of it like a home address, but for data. IPv4 is the traditional system and uses a 32-bit format (e.g., 192.168.1.1). These addresses were originally grouped into “classes” based on network size.

IPv4 Classes (quick breakdown):

Class A (0.0.0.0 – 127.255.255.255)
• Built for very large networks
• Supports millions of hosts
• Private range: 10.0.0.0 – 10.255.255.255

Class B (128.0.0.0 – 191.255.255.255)
• Medium to large organizations
• Private range: 172.16.0.0 – 172.31.255.255

Class C (192.0.0.0 – 223.255.255.255)
• Small networks (homes, SMBs)
• Private range: 192.168.0.0 – 192.168.255.255

Class D (224.0.0.0 – 239.255.255.255)
• Used for multicast traffic

Class E (240.0.0.0 – 255.255.255.255)
• Experimental / research use

Key reserved ranges:

0.0.0.0 → default route / unspecified address
127.0.0.1 → loopback (localhost)

Private vs Public IPs:

🏠 Private IPs

• Used inside local networks
• Not reachable directly from the internet
• Common: 10.x.x.x, 172.16–31.x.x, 192.168.x.x

🌍 Public IPs

• Assigned by ISPs
• Routable on the internet
• Used for global communication

Important note: modern networks mostly use CIDR instead of classful addressing, but these classes still matter for understanding fundamentals, troubleshooting, and certification prep.
