TryHackMe for Networking

Hey everyone,

I’ve been working with a small team on switchlab.dev, a free networking lab platform we’re trying to build for people studying networking.

It’s completely free right now, and there’s no email capture, no sign up wall, and no catch. We’re just trying to get honest feedback from the networking community.

The idea is to create something that feels closer to working on real Cisco equipment, not just a basic command simulator. We’ve been spending a lot of time learning how the underlying switching/routing behaviour should actually work so the labs feel useful and realistic.

Right now we’re focusing on things like:

* VLANs

* trunking

* STP

* MAC address learning

* switching behaviour

* basic routing concepts

* troubleshooting workflows

It’s definitely still early, and I don’t want to oversell it. There’s a lot we still need to improve, but we’re trying to build this with the community in mind.

When I was studying for the CCNA, hands-on practice made the biggest difference for me. Breaking things, fixing them, and actually seeing why something works is where a lot of the learning clicked. That’s the kind of experience we’re trying to make more accessible.

We’d really appreciate honest feedback from people studying for CCNA/CCNP or anyone who teaches or works in networking.

Feel free to try it, break it, and tell us what feels wrong.

Thanks everyone.

Been studying for CCNA and subnetting was the one thing that kept tripping me up.

I built a practice tool to just drill it repeatedly.

What it does:

Generates a random IP/CIDR or you can enter your own

You solve: network address, first host, last host, broadcast, next subnet, previous subnet

Each field is graded independently so you can see exactly which part you're getting wrong

No timer pressure unless you want it just pure repetition

Free, no account, no ads. Works on mobile too.

Happy to answer questions or take feedback if something's off or missing. Frankly building it helped more then anything.
