For a long time, I thought a proper homelab needed segmentation to be responsible and professional, and setting up VLANs was the next obvious step. From all the Reddit threads and self-hosting forums I visited, I noticed the same thing: every advanced homelab seemed segmented. There was always an IoT VLAN, a trusted VLAN, and a guest VLAN. The more segments there were, the more serious it looked, and the complexity looked like maturity.
