# Public IP features and limits
> Public IP features, IPv4/IPv6 support, pricing for auto-assigned and reserved IPs, regional pools, and per-VM and per-account limits
Updated May 8, 2026
## Features
### Address families
* **IPv4** — standard public IPv4, available in every region. Reserved at **\$3 / month**
* **IPv6** — single public IPv6, available in every region. Reserved at **\$1 / month** (cheaper than IPv4 — IPv6 address space isn't scarce)
* **Dual-stack** supported — a VM can have one IPv4 and one IPv6 simultaneously
### Two lifecycles
* **Auto-assigned** — free pool IP, returns to pool on detach. Free while attached
* **Reserved** — IPv4 \$3/month, IPv6 \$1/month, persists through VM rebuilds and detaches, movable between VMs
See [Auto-assigned vs reserved](/products/network/public-ips/concepts/reserved-vs-ephemeral) for the full lifecycle model.
### Where they're managed
* **Networking → Public IPs tab** — account-wide list, reserve, auto-assign, attach, detach, release
* **VM detail → Network tab** — per-VM view, add/remove IPs, attach Firewall to a specific IP
* **Networking → Diagram** — visual map, click the IP chip floating above a VM for Copy IP / Detach actions
### Firewall integration
* Each public IP can have **one Firewall attached** to filter inbound traffic
* Attach via the IP card on a VM's Network tab (`Firewall: None / Attach`)
* See [Firewall](/products/network/firewall) for rule-set creation
### Movability (reserved only)
* Detach from one VM, attach to another in the same region — the address stays the same
* Standard pattern for blue/green deploys, manual failover, partner-whitelist preservation
* Auto-assigned IPs are **not** movable — detach returns them to the pool
## Pricing
| Type | Rate |
| ------------------------------------------------------------ | ------------------------------------------------------------------ |
| **Auto-assigned IPv4 / IPv6** (attached) | **Free** |
| **Auto-assigned, detached** | N/A — auto-assigned IPs are never detached without being released |
| **Reserved IPv4** (attached or unattached) | **\$3.00 / month** (\$0.0069/hr) |
| **Reserved IPv6** (attached or unattached) | **\$1.00 / month** (\$0.0023/hr) |
| **Yearly lock-in** | \$36/yr (IPv4) / \$12/yr (IPv6) |
| **24-month lock-in** | \$72/2yr (IPv4) / \$24/2yr (IPv6) |
| **Additional IPs beyond the dashboard limit** (support-only) | Same per-IP rate by family — IPv4 \$3/mo, IPv6 \$1/mo |
| **Gateway IPs** (Platform Router, Firewall Appliance WAN) | Free with Platform Router; rolled into Firewall Appliance VM price |
Yearly and 24-month durations are the **same effective per-month price as monthly** — they lock the rate (no surprise increases) but offer no volume discount today. For the picker walkthrough, see [Reserve a static IP → Billing Period](/products/network/public-ips/quickstart-guides/reserve-ip#3-billing-period).
Reserved IPs accrue continuously whether attached or not. If you delete a reserved IP mid-cycle, the unused days are credited back to your account balance — same prorated-on-delete model as VMs and volumes. See [Billing model](/products/build/virtual-machines/concepts/billing-model).
There is **no charge for outbound traffic on a public IP** at the IP layer — you're billed for VM bandwidth (which is free on Raff today) and for Object Storage public-internet egress when applicable. The IP itself just costs the reservation fee.
## Limits
| Item | Limit |
| ------------------------------------ | --------------------------------------------------------------------------------------------------------- |
| **Public IPv4 per VM (dashboard)** | **1** — one IPv4 from the dashboard |
| **Public IPv6 per VM (dashboard)** | **1** — one IPv6 from the dashboard |
| **Public IPs per VM (with support)** | More on request — \$3/month per additional IP |
| **Reserved IPs per account** | No hard cap published; subject to overall account capacity |
| **Region scope** | Each IP is bound to **one region** — non-portable across regions |
| **IP-type swap on a VM** | A VM can't simultaneously hold two IPv4s from the dashboard, or two IPv6s — remove the existing one first |
| **Time to attach/detach** | Seconds — propagates through cloud-init / DHCP within a few seconds |
## Regional availability
| Region | Status |
| ------------- | ------------------------------------------------ |
| **US East** | Available today — both IPv4 and IPv6 |
| Other regions | Coming with the rest of the multi-region rollout |
The auto-assign pool is **per region** — you can only auto-assign IPs in regions where the VM lives. Available pool sizes are surfaced as the **Available in pool** stat at the top of the Public IPs tab; if it's zero for a region, auto-assign returns an error and you'll need to either wait for capacity or reserve an IP instead.
## What's not available today
* **Anycast IPs** — single IP that's announced from multiple regions
* **BYOIP / IP import** — bringing your own AS-prefixed IP block
* **Floating Virtual IP (VRRP-style)** between VMs without a manual detach/attach — the move-IP pattern is the closest equivalent
* **Per-IP tagging or notes** — coming with the broader resource-tags rollout
