Understanding Network Protocols

Network protocols enable communication between devices. A solid understanding of how these protocols work ensures smoother deployments and quicker diagnoses of problems.

Familiarise yourself with the following essentials:

• TCP/IP Protocol Suite: This is the backbone of internet communications. TCP ensures reliable data delivery, while IP handles addressing and routing.
• DNS (Domain Name System): Understand how domain names like "example.com" resolve to IP addresses. This knowledge is critical when diagnosing connectivity issues.
• DHCP (Dynamic Host Configuration Protocol): Learn how devices automatically obtain IP addresses and configurations when joining a network. This is especially helpful for large-scale systems.

IP Addressing Essentials

IP addressing is the starting point for most networking tasks. Every device in a network requires a unique IP address to communicate with others. Understanding the hierarchy and structure of these addresses is an essential skill, especially when working on complex systems.

It is important to familiarise yourself with the following:

• Learn the difference between IPv4 and IPv6. While IPv4 addresses are still widely used, the industry is rapidly transitioning toward IPv6 due to its support for a significantly greater number of devices.
• Subnetting is particularly important. For example, if you’re managing a corporate network, dividing it into subnets improves efficiency, reduces congestion, and makes troubleshooting easier. Practice dividing an IP range into smaller subnets using tools like Cisco Packet Tracer or GNS3.

 You can put these fundamentals to the test by: 

• Configuring IP ranges for home networks. 
• Setting up static routes on routers to control traffic paths.
