# ASN定位

我們的住宅代理支持通過 ASN 編號進行定位，這意味著您可以選擇來自特定運營商的代理。 您需要在請求中輸入所需的 ASN 編號。 以下是 Free SAS 的示例，其 ASN 編號為 AS12322：

`td-customer-USERNAME-country-fr-asn-AS12322`

{% hint style="success" %}
[**點擊此處**](https://vip-upload.thordata.com/files/file/the_list_of_ASN.xlsx) 下載完整的ASN列表
{% endhint %}

住宅代理池是輪換的，因此在特定時間內可能沒有可用的IP供特定ASN使用。如果發生這種情況，您將收到錯誤響應。在這種情況下，請嘗試針對其他ASN。

{% hint style="danger" %}
ASN 參數必須與國家參數一起使用，不能單獨指定。
{% endhint %}
