Kevin Nanns / Enterprise Network Architect
I love networking.Let's make it make sense.
I explain how networks work and share practical things I've learned from doing the job. Routing, switching, Wi-Fi, troubleshooting, and labs, for network engineers and people learning to become one.
- Packet captures
- Logs and settings
- Controlled tests
- Real devices and gear
Explore networking
There's a lot of cool stuff happening between two devices.
- 01
What happens to a packet when it leaves your computer?
- 02
What does a VLAN actually separate?
- 03
How do you figure out where a connection is failing?
- 04
What can you build and break in your own lab?
Learn it. Try it.
Networking makes more sense when you can see it work.
Follow a packet. Read a routing table. Change something in a lab and see what happens. I teach the basics in a way you can follow, then connect them to the decisions and problems you run into on a network.
