IPAM (Proxmox)
IPAM (IP Address Management) for Proxmox in CMP is a CMP-level capability. Proxmox does not provide the IP pool, allocation tracking, or billing subscription lifecycle that CMP uses for customer VMs — CMP owns that layer.

CMP-level, not Proxmox-native
| Layer | Responsibility |
|---|---|
| Proxmox | Provides the network interface (Linux bridge) the VM attaches to. It does not manage CMP’s allocatable IP catalogue. |
| CMP IPAM | Builds and tracks the IP pool, marks available / allocated addresses, and drives IP billing when enabled on the synced network |
Admins define subnet fields (Cidr, Subnet Mask, Gateway IP) when importing or editing a network in CMP. CMP then generates (or accepts manually entered) IPs into the IPAM list for that network.
Synced Proxmox bridge + CMP subnet / Generate IPs → CMP IPAM pool → Allocate on VM create / attach
Proxmox networking is bridge-centric. CMP needs a consistent way to show customers which IPs are free, assign an IP at provision time, and optionally create an IP Address subscription. That bookkeeping lives in CMP — see Networks IP Address (IPAM).
What IPAM covers
- Generate IPs from CIDR / mask / gateway (or enter IPs manually)
- Pool visibility under Networks IP Address (available vs allocated)
- Allocation when a customer creates a VM or attaches a billable network
- Optional Associated IP Address for display of public ↔ private NAT mapping (manual today — CMP does not configure NAT on Proxmox)
CMP does not validate that mapped IPs match the real VLAN / routing on Proxmox. Keep pools aligned with your actual network design. Associated IP / NAT automation is on the Proxmox roadmap.
Billing vs IPAM
| Concern | Where |
|---|---|
| Which IPs exist / are free | CMP IPAM (this feature) |
| How much an IP costs | IP Address package |
| Whether this network creates an IP subscription | Per-network enable IP billing — Shared Network IP Billing |
IPAM can track addresses even when billing on that network is No. Billing only starts when IP billing is Yes and the package is priced.
Prerequisite: sync the network first
IPAM is attached to a synced Proxmox network. CMP does not provision the bridge — see Networks (sync only).
- Create the Linux bridge on Proxmox
- Import / sync into CMP
- Generate or enter the IP pool → manage under Networks IP Address
