# Public IPs
> Public IPv4 and IPv6 addresses on Raff — auto-assigned from a free pool by default, or reserved as static IPs that persist across VM rebuilds for $3/month (IPv4) or $1/month (IPv6)
Updated May 8, 2026
A **Public IP** on Raff is a routable IPv4 or IPv6 address attached to a VM (or to a VPC's Internet Gateway) so it can be reached from the public internet. Every VM you create comes with one auto-assigned IPv4 from the regional pool — free for as long as it's attached. You can also **reserve** a static IP that stays yours across VM rebuilds and detaches, billed at **\$3/month for IPv4** or **\$1/month for IPv6**.
There are two distinct lifecycles for a public IP on Raff, and the difference matters:
| | **Auto-assigned** | **Reserved** |
| --------------------------------------- | ----------------------------------------------------- | ------------------------------------------------------------------------- |
| **Cost** | Free while attached | \$3/month (IPv4) or \$1/month (IPv6), billed continuously |
| **What happens when detached** | Returns to the regional pool — anyone may get it next | Stays yours, unattached, ready to re-attach to any VM |
| **What happens when the VM is deleted** | Released to the pool | Survives, stays yours |
| **Use it for** | Default VM internet access | Stable address you reference in DNS / firewall rules / partner whitelists |
If your VM was rebuilt every Tuesday, an auto-assigned IP would change every Tuesday. A reserved IP would stay the same forever.
The dashboard surfaces public IPs in two places: the **Public IPs** tab on the Networking page (account-wide list, where you reserve and auto-assign) and the **Network** tab inside each VM's detail page (where you add, remove, or firewall that specific VM's IPs).
## What you can do
| Task | Where |
| -------------------------------------------------- | ----------------------------------------------------------- |
| Give an existing VM a public IP from the free pool | Networking → Public IPs → **Auto-assign IP** |
| Reserve a static IP you'll keep across VMs | Networking → Public IPs → **+ Reserve IP** |
| Add or remove a public IPv4 / IPv6 on one VM | VM detail → **Network** tab |
| Move a reserved IP between VMs | Detach from VM A → attach to VM B |
| Add a Firewall to a public IP | VM detail → **Network** tab → IP card → **Attach** firewall |
