}VM network attachments
Attach floating IP to VM
Attach a floating public IP to a virtual machine. Pick one of two modes:
Option A — attach a reserved IP (use ip_id)
Pass ip_id set to a previously reserved IP (from POST /api/v1/ips/reserve or GET /api/v1/ips?reserved=true). The IP must:
- belong to the same account
- not be currently attached to another VM
- have
reserved: true
No new billing on attach — you’re already paying for the reserved IP.
A VM can hold up to 4 public IPv4 addresses. The first IPv4 on a VM becomes its primary address; additional IPv4s must be reserved IPs attached with ip_id.
Option B — auto-assign a new IP (use type)
Leave ip_id empty and pass type to allocate a fresh IP from the pool:
type: IPv4(default if omitted)type: IPv6
Auto-assign is available only while the VM has no public IP of that family, and the IP is included with the VM at no extra charge. It is not reserved: detaching releases it back to the shared pool.
Notes
- Auto-assign (
type) fails if the VM already has a public IP of the same family — attach a reserved IP (ip_id) to add more IPv4s, up to 4 total. - Optionally pass
security_groups(UUID array) to apply security groups to the new NIC.

Authorizations
API key for authentication. Each key is bound to a specific account.
Headers
Project ID. Required for all mutating operations (create, delete, power actions, resize).
Path Parameters
VM ID (UUID)
Body
application/json
Provide either ip_id (attach an existing reserved IP) or type (auto-allocate a new IP). Don't combine — ip_id takes precedence and type is ignored when both are sent.
ID of a previously reserved IP. The IP must belong to the same account, be reserved, and not already attached to another VM. No new billing on attach — you're already paying for the reserved IP. Use this to add up to 4 public IPv4 addresses to a VM.
IP family to auto-allocate. Used only when ip_id is omitted. Defaults to IPv4. Available only while the VM has no public IP of that family; the IP is included with the VM at no extra charge and is released back to the pool on detach.
Available options:
IPv4, IPv6 Security group IDs (UUIDs) to apply to the new NIC.
