Key Principles for this Pillar

  • DHCP reservations guarantee your server always retains the exact same local IP address.
  • Local DNS lets you access services via friendly URLs like http://immich.home instead of IP numbers.
  • VLANs allow you to isolate untrusted IoT gadgets (smart plugs, cheap cameras) from your private server.
  • Ethernet cables are always superior to Wi-Fi for 24/7 server stability and throughput.
