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 — you’re already paying for the reserved IP.

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

A new IP is allocated and billed to your account from the moment of attach. Detach to release it back to the pool.

Notes

VM must not already have a public IP of the same family (detach first).
Optionally pass security_groups (UUID array) to apply security groups to the new NIC.

Authorizations

X-API-Key

string

header

required

API key for authentication. Each key is bound to a specific account.

Headers

X-Project-ID

string<uuid>

required

Project ID. Required for all mutating operations (create, delete, power actions, resize).

Path Parameters

string<uuid>

required

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.

ip_id

string<uuid>

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 — you're already paying for the reserved IP.

type

enum<string>

IP family to auto-allocate. Used only when ip_id is omitted. Defaults to IPv4. A new IP is allocated from the pool and billed to your account from the moment of attach.

Available options:

IPv4,

IPv6

security_groups

string<uuid>[]

Security group IDs (UUIDs) to apply to the new NIC.
