# 如何定位特定的城市？

1、您可以在**端點產生器**中，選擇城市列表並在列表中選擇您需要指定使用的城市即可。

{% endhint %}

2、您還可以通過添加`city`參數並在參數後添加城市名稱，指定使用某個城市的IP

例如：使用來自美國華盛頓的隨機IP地址對`ipinfo.thordata.com`執行查詢

```sh
curl -x t.pr.thordata.net:9999 -U "td-customer-USERNAME-country-US-city-washington:PASSWORD" ipinfo.thordata.com
```

{% hint style="info" %}
