TechEd and IP Addresses

I’m starting to move more into the area of tech-focused micromaterials, and this is part of a large shift towards a focus on TechEd. Does that term already exist? I googled around a bunch and couldn’t find any association with the way I’m using it, so I’m just gonna keep using it until somebody is actually paying enough attention to correct me.

Instead of EdTech (meaning using technology for general educational goals), I’m going to be pivoting to TechEd (meaning educational materials for tech, mostly website developers). There’s a lot more interest in that space at the moment, and I think the intended audience is technical enough to grasp the merits that automation can bring.

Where I might have a bit harder time explaining the benefits is in terms of the pedagogical principles, but if I have some working examples that people actually use and find helpful, then the theoretical arguments don’t matter as much.

I previously created a few git-based micromaterials, which are exactly TechEd, though until now, all my efforts have been based around using the console (sometimes called the terminal), which isn’t very mobile-friendly. If one of the guiding principles of micromaterials is that they are available anytime/anywhere, then we need to have things that learners can use in the browser.

So I’ve created my first browser-based tech micromaterial! I had to name it something, so I went with IPinder…kind of like IP + tinder.

The interaction is very straightforward. If you think the IP address is public, you can swipe right, otherwise, if you think it’s a private IP address (really, just not public, since some of the IP ranges are reserved ranges that aren’t really used in private subnets), then swipe left.

For the desktop view, it’s a click rather than a swipe (Swiping isn’t super common on desktop, which is why I used clicks for the larger screen size).

As a micromaterial, the feedback on the activity needs to be specific and immediate. If you get it correct, a nice green tick shows up. If you get it wrong, a red X, along with the reason shows up.

Not to worry if you forget which ranges aren’t public…the helpful modal from clicking the question mark icon in the upper right will show you the necessary refresher info!

Basically, I want to improve my knowledge of networking, and being familiar with the reserved IP address ranges is a big part of diagnosing connectivity issues, so I made this micromaterial (mostly) for myself.

Eventually, I hope to have a lot more TechEd micromaterials (including ones focusing on vocabulary of tech, simple functions, and security aspects), and even a simple curriculum with progress reports.
