Home Lab tips

🏠

Splitting your home network into VLANs (IoT, guest, trusted)? Use /26 or /27 subnets to keep each segment right-sized.

💡

Docker default bridge networks and Kubernetes pods use private ranges — check overlaps with the 10.x and 172.16-31.x presets.

🎯

A /30 is perfect for point-to-point links between routers (2 usable hosts).
