## GET /api/v2/vps/{id}/routed-ipv6

**Get routed IPv6 state**

Return routed IPv6 availability, current allocation, suggested next hop, parent prefix, and cooldown rules. If `available` is false, use `reason` instead of guessing from network interfaces.

### Related Endpoints

- `POST /api/v2/vps/{id}/routed-ipv6`: Allocate or refresh routed IPv6
- `DELETE /api/v2/vps/{id}/routed-ipv6`: Release routed IPv6
- `GET /api/v2/vps/{id}`: Get VPS details

### Headers

- `Accept`: application/json
- `Authorization`: Bearer YOUR_API_KEY
- Required API scope: `read:vm`

### Parameters

- `id` (path, string, required): Public VPS ID. Get it from GET /api/v2/vps `data[].id`. Do not invent this value; use the exact ID returned by the referenced API response. Example: `vps_01hxa3b4c5d6e7f8g9h0j1k2m3`
