# ASN 定位

{% hint style="warning" %}
我们的 ASN 定向参数仅在完成 KYC 流程后可用。请联系客户支持或您的客户经理以请求访问权限。
{% endhint %}

我们的移动代理支持按 ASN 编号进行定位，这意味着您可以从特定运营商中选择代理。您需要在请求中输入所需的 ASN 编号。以下是 T-Mobile 的示例，其在美国的 ASN 编号为 21928：

`customer-username-ASN-21928-sessid-abcde12345:password`

您可以找到 ASN 号码 [**这里**](https://asnlookup.com/)**.**

移动代理池本质上是动态的，因此如果当时该特定 ASN 下没有 IP，您将收到一个 `502 Bad Gateway` 响应代码。在这种情况下，您应尝试另一个 ASN 号码。

{% hint style="info" %}
您可以在每个请求中使用国家或 ASN 参数中的任意一个。如果同时使用这两个位置参数，则只会应用国家参数。
{% endhint %}
