Primary IPs assignee_type behavior change

In the create Primary IP call, the assignee_type argument is now only send when the assignee_id argument is set. The assignee_type argument will stop defaulting to server in the near future, consider explicitly setting this argument when needed.

As of 1 August 2026, the behavior of the Primary IP assignee_type property will change, and will return unassigned when the Primary IP is not assigned (when assignee_id is null). The goal is to eventually assign Primary IPs to other resource types, not only to server.

See the changelog for more details.

In addition, the Primary IP request body assignee_type property of the operation POST /v1/primary_ips is now optional. Primary IPs created without assignee_type return server until 1 August 2026, after this date, its value will be unassigned.

See the changelog for more details.

### Primary IPs `assignee_type` behavior change

In the create Primary IP call, the `assignee_type` argument is now only send when the `assignee_id` argument is set. The `assignee_type` argument will stop defaulting to `server` in the near future, consider explicitly setting this argument when needed.

As of 1 August 2026, the behavior of the Primary IP `assignee_type` property will change, and will return `unassigned` when the Primary IP is not assigned (when `assignee_id` is `null`). The goal is to eventually assign Primary IPs to other resource types, not only to `server`.

See the [changelog](https://docs.hetzner.cloud/changelog#2026-04-27-primary-ips-will-return-unassigned) for more details.

In addition, the Primary IP request body `assignee_type` property of the operation [`POST /v1/primary_ips`](https://docs.hetzner.cloud/reference/cloud#tag/primary-ips/create_primary_ip) is now optional. Primary IPs created without `assignee_type` return `server` until 1 August 2026, after this date, its value will be `unassigned`.

See the [changelog](https://docs.hetzner.cloud/changelog#2026-04-27-primary-ips-make-assignee_type-optional) for more details.
