# `IP_LIST_LIMIT_REACHED` (HTTP 409): the account already holds as many IP lists as it may

A new allow or deny list was asked for when the account already holds the maximum number of lists.

An account keeps a bounded number of IP lists, published as `meta.max_lists` on `GET /api/v1/ip/lists`, because every list is packed and scanned on every IP lookup the account makes. The entries themselves are the thing to grow: one list holds up to `meta.max_entries` addresses and prefixes.

Nothing is created and nothing is charged.

**What to do.** Add the entries to a list you already have with `PATCH /api/v1/ip/lists/{listId}`, or remove a list you no longer need with `DELETE /api/v1/ip/lists/{listId}` and create the new one.

```json
{
    "success": false,
    "error": {
        "code": "IP_LIST_LIMIT_REACHED",
        "message": "This account already holds 20 IP lists. Remove one, or add the entries to a list you have.",
        "request_id": "req_01m1kgdm4xngzmbmff68g94w0c"
    }
}
```
