Kevin Nanns / Enterprise Network Architect
Let's figure outhow technology works.
Demystify technology and make learning it accessible to everyone. That's the goal, whether we're exploring how a device works, fixing a connection, or trying something in a lab.
- Packet captures
- Logs and settings
- Controlled tests
- Real devices and gear

Things worth figuring out
What's actually happening here?
- 01
How does data get from your computer to a website?
- 02
What are you agreeing to when you accept website cookies?
- 03
How do you figure out where a connection is failing?
- 04
What can you build and test in a home lab?
Learn it. Try it.
Try a change. See what happens.
A lab is a setup for trying things out. Follow the data between two devices, change one setting, and compare the results. I explain what we're looking at and what it tells us.
