Networking

Here’s a thing I’ve quietly hated for years: managing static IP assignments and DNS names for the little fleet of gear on my network. Every homelab has it — the Pi in the garage, the shop printer, the sensor node in the attic, the pool controller. You want them at known addresses with known names. And the “old-school” way to get that is to stand up a DHCP server and a DNS server and keep them in sync. Since my network has tens of BrightSign devices in addition to my hobby robotics devices, this becomes actual work.

SSH tunnels are basically indistinguishable from magic.
