# VM static IPs — router DHCP reservations (pve10)

Proxmox **LXCs** use `pct set … ip=10.0.10.X/24` (done for 210, 215–219).

**VMs** without cloud-init are pinned by **router DHCP reservation by MAC** (Method B in plan-2).
Ansible **cannot log into your router** — configure static leases in the UI.

**Your UniFi:** https://192.168.2.1/ — step-by-step: [unifi-static-dhcp.md](unifi-static-dhcp.md).

Homelab guests use **`10.0.10.0/24`** (gateway `10.0.10.1`). If UniFi also serves `192.168.2.x`, ensure the `10.0.10.x` segment is the network those VMs/LXCs use
(or that routing/DHCP relay matches your Proxmox bridge).

## How to add a reservation (any router)

1. Open router admin (UniFi: **https://192.168.2.1/**).
2. Find **DHCP** / **LAN** / **Static leases** / **Reserved addresses**.
3. For each row: **MAC address** → **IP address** → Save.
4. Reboot guest or renew DHCP (`dhclient -r && dhclient` on Debian) if IP does not update immediately.
5. Mark done in [host-list.md](host-list.md).

After reserving in the router, mark **DHCP/Static** as `✅ router` in [host-list.md](host-list.md).

In-guest static (optional, stronger): SSH as root and set `/etc/network/interfaces` like caddy VM 106.
