IPv6 Addresses and IPv6 Subnets
This page covers the two IPv6 pool screens. It is written for the operator selling extra IPv6 hosts or routed prefixes. List, assign, release, and delete behave like IPv4 Addresses. This page documents only what changes.
IPv6 Addresses
Menu: Addons → Proxmox Suite → Resource → Network → IPv6 Addresses
IP type is locked to IPv6. Placeholder for Network address: 2001:db8::/64.
| Rule | What the form does |
|---|---|
| Network | Required. Network address is required for IPv6. The value must look like a prefix, for example 2001:db8::/64. |
| First IP / Last IP | Shown, and ignored. Hosts are generated from the prefix. |
| Host count | Not a field. The create request defaults to 64 hosts and the expander stops at 256. |
| Number of subnets / Subnet CIDR | Hidden. |
Details (virtualization, cluster, nodes, bridge, trunks, tag, private) match IPv4.
IPv6 Subnets
Menu: Addons → Proxmox Suite → Resource → Network → IPv6 Subnets
IP type is locked to IPv6 Subnet. You carve child prefixes from a parent allocation.
| Field | Type | What it does |
|---|---|---|
| Network address | Text | Parent prefix, for example 2001:db8::/48. Required. |
| Number of subnets | Number, minimum 1, default 64 | How many children to create. Cap 256. |
| Subnet CIDR | Text, placeholder 64 |
Length of each child. Must be 1–128 and longer than the parent. |
| First IP / Last IP | Text | Relabelled First subnet / Last subnet in the browser, and ignored by the server. |
| Condition | Message |
|---|---|
| No parent | Network address is required for IPv6 subnet. |
| Bad child length | Subnet CIDR must be between 1 and 128. |
| Child not longer than parent | Subnet CIDR must be longer than the parent prefix. |
Example
A /48 sold as /64 networks: IPv6 Subnets, network 2001:db8::/48, Number of subnets 16, Subnet CIDR 64, Confirm. Point the policy IP pools multi-select at that pool when the package limit IPv6 subnets is greater than zero.
