About Me

Well, hello there! Welcome to NodeConnect. My name is Zach. Are you new to the networking scene? My road to networking was sparked by a short-lived interest in electrical engineering. Yes, pun intended. My focus has shifted from that field, but it led me down another path: how data travels from point A to point B (to point C, point D, etc.)

I graduated with a Bachelor's in Information Technology. Along the way, I learned to work with different hardware and software, earned leading industry certifications such as Network+, started my own home lab, and wrote notes in a way that helped me connect concepts more clearly. I hope this will do the same for you.

I started NodeConnect as a blog to explain foundational networking concepts. From my research, I have found it helpful to begin somewhere, and where else is better than starting at the backbone of information transfer. You will see networking concepts explained, my successes and failures, helpful notes, and my home lab chronicles.

Are you a seasoned professional? If so, welcome as well. I hope this site offers a fresh perspective, but I also look forward to learning from you. As you know, the industry is always changing, with more emphasis on utilizing AI, automation, and the cloud. Please do share your experience!

No matter who you are, thank you for visiting. Feel free to reach out. I’d love to hear your thoughts, feedback, or just want to share some subnetting secrets. I'm all for it.

How to Set Up a Cisco Router as a DHCP Server (Step-by-Step Guide)

Lab time! Want to build a DHCP server?  In this lab, I will show you how to build your own DHCP server on a router using Cisco Packet Tracer, as shown above. By the end of this post, you will be able to create your own DHCP server with a Cisco 2911 router, perhaps in a home lab setting, and prepare you to build your own on other hardware.  Why a Router?  A DHCP server is a centralized, automated service that assigns important network configuration details to devices on a network, such as IP addresses. Without it, we would have to create manual entries for our entire network, which can be time-consuming and lead to errors. Traditionally, there are dedicated servers to handle these functions. There are many ways to implement a DHCP server in your topology, including a dedicated physical server, a virtual machine, cloud-based gateways, and firewalls. However, there are specific benefits to using a router as your DHCP server: Reduced infrastructure: While havi...

How Reserving a Pavilion Explains DHCP

It’s party time! You decide to throw a party at a park with a bunch of pavilions. But you can’t just walk up and claim a pavilion. Instead, you have to go through the park’s reservation service. You tell them the date and time of your event, and they check their list to see what’s available. Great news! A pavilion is open, and they assign it to you for a set time. The day arrives, and as planned, you host your party until it’s time to leave. What a great gathering! This is a lot like how DHCP works in a network. When a device — like your phone or laptop — joins a network, it can’t just start communicating. It needs an IP address first, just like you needed a reserved pavilion. Then, what is the "reservation" process of getting an IP address? Let's take a dive into the automated world of DHCP. What is DHCP? The Dynamic Host Configuration Protocol simplifies network provisioning by automatically assigning important network parameters. These include: IP addresses : Just as ...

Subnets: Key to Network Organization

Whether it is a to-do list or a big project, organization is key. We have busy lives. The task in itself can have several parts or may require some sort of collaboration with a partner or a team. A project may call to meet deadlines, which means keeping up with those crucial dates and having a system of order. Similarly, our networks are busy, transferring a great deal of data across links and nodes. The amount of traffic generated can lead to bottlenecks, packet loss, and delays. A network’s design can vary in complexity, depending on the environment or needs of a customer. Just as we find a manageable way to handle heavy workloads, our networks have a way of efficiently handling network traffic by creating "mini-networks" within our network. This process is called subnetting.   Why We Subnet To reduce congestion. Just as traffic in cities cause slowdowns and delays, too much traffic can lead to bottlenecks, packet loss, and delays. Subnetting breaks the netwo...
