# Realización de solicitudes

De forma predeterminada, los Proxies de Oxylabs y Proxy Rotator usan una [**autenticación HTTP**](https://en.wikipedia.org/wiki/Basic_access_authentication) básica que requiere que proporciones un nombre de usuario y una contraseña. Puedes obtener tus credenciales contactando a tu Dedicated Account Manager o a nuestro equipo de soporte en [**support@oxylabs.io**](mailto:support@oxylabs.io).

También ofrecemos compatibilidad con autenticación basada en direcciones IP incluidas en lista blanca; consulta [**Lista blanca de IPs**](/products/es/proxies/dedicated-isp-proxies/enterprise/restful.md). Según tu método de autenticación, puede que necesites cambiar el puerto del proxy.

| Puerto del proxy | Uso                                                                                                                                                                                                                                                                                                                      |

| `60000`          | Este puerto es necesario con los Proxies cuando se usan credenciales de inicio de sesión (nombre de usuario y contraseña). También se usa con [**Proxy Rotator** ](/products/es/proxies/dedicated-isp-proxies/enterprise/proxy-rotator-optional.md)con credenciales de inicio de sesión e IPs incluidas en lista blanca. |
| `65432`          | Requerido con los Proxies cuando la autorización se realiza mediante IPs incluidas en lista blanca.                                                                                                                                                                                                                      |

#### Ejemplos de código

Si quieres usar Dedicated ISP Proxies mediante el método de autenticación con nombre de usuario y contraseña:

{% tabs %}
{% tab title="cURL" %}

```shell
curl -x 1.2.3.4:60000 -U user1:pass1 http://ip.oxylabs.io/location
```

{% endtab %}

{% tab title="PHP" %}

```php
<?php
    $username = 'user1';
    $password = 'pass1';
    $proxy = '1.2.3.4:60000';
    $query = curl_init('https://ip.oxylabs.io/location');
    curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($query, CURLOPT_PROXY, "http://$proxy");
    curl_setopt($query, CURLOPT_PROXYUSERPWD, "$username:$password");
    $output = curl_exec($query);
    curl_close($query);
    if ($output)
        echo $output;
?>
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

response = requests.get(
    'https://ip.oxylabs.io/location',
    proxies={'http': 'http://username:password@1.2.3.4:60000',
            'https': 'http://username:password@1.2.3.4:60000'}
)
print(response.text)
```

{% endtab %}

{% tab title="C#" %}

```csharp
using System;
using System.Net;

class Example
