Tool of the Day
One tool. What it is, why it matters, and how to actually use it.
NetBox
Your network's source of truth — document every device, IP, and cable before you forget what plugs into what.
What it does
NetBox is an open-source DCIM (Data Center Infrastructure Management) and IPAM (IP Address Management) platform originally built by the networking team at DigitalOcean. It gives you a structured, searchable inventory of all your network devices, IP prefixes, VLANs, racks, cables, and sites. Think of it as the single place where your network documentation actually lives and stays current.
Why you need it
Without a source of truth, homelabs turn into a maze of sticky notes and half-remembered subnets. NetBox lets you track exactly where every FortiGate interface, Arista switch, or MikroTik router sits in your topology, which IPs are allocated where, and how your VLANs map to physical connections. When something breaks at 2am, you'll thank yourself for having it.
How to use it
- 01Step 1: Clone the netbox-docker repo: git clone -b release
