# Seleccionar país

Aprende a segmentar ubicaciones específicas de proxy y a usar la lógica de rotación.

Si quieres acceder a IPs de ubicaciones específicas, debes proporcionar un `país` – parámetro con un código de país de dos letras en tu nombre de usuario Aquí está la lista de `país` parámetros. Por ejemplo, si quieres usar el parámetro de país de Estados Unidos, añade `country-US`.

Encuentra la lista completa de países admitidos en la tabla de abajo.

Por ejemplo, si quieres rotar solo el grupo de proxies de Estados Unidos, usa el puerto rotatorio `8000` junto con un parámetro `country-US` en tu nombre de usuario:

```bash
curl -x dc.oxylabs.io:8000 -U 'user-USERNAME-country-US:PASSWORD' https://ip.oxylabs.io/location
```

#### Diferencias entre los métodos de suscripción

`Datacenter por IP` los usuarios que proporcionen el puerto rotatorio y `país` el parámetro recibirán una **IP aleatoria del país seleccionado de su lista de proxies** con cada nueva solicitud.\
\
`Datacenter por tráfico` los usuarios que proporcionen el puerto rotatorio y `país` el parámetro recibirá **una IP aleatoria del país seleccionado de todo el grupo de proxies.**

{% hint style="info" %}
Usamos la [**MaxMind GeoIP2**](https://www.maxmind.com/en/geoip2-databases) base de datos para determinar la ubicación de las IPs.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developers.oxylabs.io/products/es/proxies/datacenter-proxies/select-country.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
