About
A working notebook, kept in public, for the parts of infrastructure I'd otherwise forget.
Subnetted is where I write down what I learn running my own infrastructure. The subjects are networking, self-hosting, homelabs, and the unglamorous plumbing that holds them together: VLANs and firewall rules, reverse proxies and DNS, the boxes humming in a closet that quietly do more than they should.
I'm a hands-on, curious sort. I like understanding a system all the way down — not just that a thing works, but why it works, and what it's actually doing on the wire when it does. That tends to mean reading the packet capture instead of trusting the dashboard, and rebuilding something from scratch once I think I understand it, just to find out I didn't.
Most of what ends up here started as a problem I had to solve and a fix I didn't want to relearn six months later. So the posts read like field notes: what broke, what I tried, the trade-offs, and what I'd do differently. I try to show the reasoning rather than hand down conclusions — if something here is wrong, it's wrong in a way you can check.
