# Planck cluster network table (2026-09-19)

All nodes: static IP configured on the node (NetworkManager, "Wired
connection 1", manual, /22, gateway+DNS 192.168.1.1 = UDM Pro).

Every node is also on the owner's Tailscale tailnet (always-on) — the second
IP is reachable from anywhere via the tailnet, including the laptop
kubeconfig (API: https://100.124.112.13:6443 = planck002's Tailscale IP,
added to k3s tls-san on all three servers).

RECOMMENDED follow-up: add these as DHCP reservations in UniFi too, so the
router never leases these addresses to other devices. (UniFi UI: each client
device → Fixed IP. API is blocked by MFA.)
