New Series: IP in Practice

Introductory picture to IP in Practice

I have done a few posts on subnetting and the inner workings of DHCP. I wanted to do a post on IPv6 and a hands-on demo on implementing DHCP on actual networking equipment. However, I missed a few parts that I would like to cover that would particularly help in understanding how IP works and why it is needed.

Unlike the previous series, this will be a direct approach to a certain protocol: Internet Protocol (IP). I recently started my first series, covering important ports, protocols, and acronyms used in the networking field. However, I realized not only is it difficult to address the ones to mention, but for some letters it's hard to find. The intended structure was to have several per letter not just one. The idea seemed fun and engaging, however, doing over 20 posts alphabetically on acronyms, ports, and protocols lacks order and deviates from the direct approach I want this blog to have. For that reason, I am putting it on hold indefinitely. It was fun at first, but it was not accomplishing my goal.

 If you have ever felt the same way about ending or pivoting from a project like I did with the A-Z series or maybe feel differently, please comment below and share your thoughts.  

Enough with the aside. The IP in Practice series will be a hands-on approach toward understanding our main line of communication used by devices today: IPv4 and the debated IPv6. This series is written from a learning and practice perspective, focusing on observing how IP behaves in real networks through study, labs, and demos. 

Let's first look at what goes into an IP address. 

IP in Practice Series
IPv4 IPv6
IP Addressing Basics Why do we need IPv6?
IPv4 Structure and Classes IPv6 Address Structure
Public and Private Addresses Address Types (unicast, multicast, anycast)
Demo Demo
Classless Addressing and Subnetting IPv6 Subnetting
IPv4 Subnetting Calculator IPv6 Prefix Lengths
Special IPv4 Addresses Special IPv6 Addresses
IPv4 Workarounds (NAT, PAT, VLSM) Transition to IPv6 (SLAAC, NAT64, Tunneling)

My Trek up Mount Net

   Networking is ...          Let me hold off on that. Expect a definition later. First, let's set the scene.         This is a new platform, new field, new everything for me. You might or might not ask yourself - how?   If you are part of the "might not", I get it. I am currently a college student just trying to make sense at staring at the daunting Mount Net - one of many peaks among the IT Mountain Range that grows not centimeters every year, but centimeters every second it seems like. Yet this is a trek I know I want to take step by step.         Let me just say, my journey to networking started a few years ago. When I graduated high school, I had different interests - psychology, math, animal science, just to name a few. I had a brief stint of interest in electrical engineering that sparked from a fascination with electricity. My mother also told me that my grandfather used to be in ...

Is MCP the TCP/IP for AI?

  The Internet runs on TCP/IP. We might as well include AI in the mix, but how about AI? TCP/IP allows devices, services, applications, and data to communicate with other devices, services, applications, and data. How does AI talk? This is why I love networking, and the thought of how AI communicates makes me hopeful that the field will survive extensive job replacements. Unless self-healing networks actually come.  I have been reading more into MCP. What exactly is it? Is it necessary for AI models and agents to communicate? Did you know AI agents have their own social media?? Biggest of all, is there any correlation between MCP and TCP/IP for model communication? Can MCP take notes from TCP/IP, or will it rewrite networking? This post explores Model Context Protocol through parallels with TCP/IP to understand how AI communication can become more structured, standardized, and consistent. What is MCP? To understand MCP, a good place to start is APIs. To understand APIs,...

Subnetting Tips

When I was first introduced to subnetting, it was difficult to understand the math and the process behind it. I watched videos but it did not click. I focused more on how to calculate it than on the reasoning behind it. Why do we subnet? I remember seeing forward slashes followed by numbers, classes, letters, network and broadcast addresses - important terms that was overshadowed by just trying to grasp why certain numbers were used.  Years later, I hear the word "subnetting" in one of my courses, and it reminded me of my struggles. Yet, I was excited. It was a time for redemption. Example after example, I started to get them right but also got to understand how to create a subnet with sufficient space for devices. Because of this, I have grown to love subnetting.  For me, it took time - a break that lasted about two years followed by a curriculum that focused on the topic for a few weeks. If you find yourself struggling with subnetting, do not worry. It takes time. If someth...
