# Making Requests

By default, Oxylabs proxies and Proxy Rotator use a basic [**HTTP authentication**](https://en.wikipedia.org/wiki/Basic_access_authentication) that requires you to provide a username and password. You can get your credentials by contacting your Dedicated Account Manager or our Support Team at [**support@oxylabs.io**](mailto:support@oxylabs.io).

We also support authentication based on whitelisted IP addresses; see [**Whitelisting IPs**](https://developers.oxylabs.io/proxies/dedicated-isp-proxies/enterprise/restful). Depending on your authentication method, you might need to change the proxy port.

| Proxy Port | Usage                                                                                                                                                                                                                                                                                |
| ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `60000`    | This port is required with proxies when login credentials are used (username and password). It is also used with [**Proxy Rotator** ](https://developers.oxylabs.io/proxies/dedicated-isp-proxies/enterprise/proxy-rotator-optional)with both login credentials and whitelisted IPs. |
| `65432`    | Required with proxies when authorization is done via whitelisted IPs.                                                                                                                                                                                                                |

#### Code examples

If you want to use Dedicated ISP Proxies via username and password authentication method:

{% 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
{
    static void Main()
    {
        var proxy = new WebProxy
        {
            Address = new Uri($"http://1.2.3.4:60000"),
            BypassProxyOnLocal = false,
            UseDefaultCredentials = false,
            Credentials = new NetworkCredential("username", "password")
        };

        var handler = new HttpClientHandler
        {
            Proxy = proxy,
        };

        HttpClient client = new HttpClient(handler);
        var task = Task.Run(async () =>
        {
            var response = await client.GetAsync("https://ip.oxylabs.io/location");
            var content = response.Content;
            var result = await content.ReadAsStringAsync();
            return result;
        });

        task.Wait();
        Console.WriteLine(task.Result);

{% endtab %}
{% endtabs %}

If you want to use Dedicated ISP Proxies via Whitelisted IP authentication method:

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

```shell
curl -x 1.2.3.4:65432 https://ip.oxylabs.io/location 
```

{% endtab %}

{% tab title="PHP" %}

```php
<?php
    $proxy = '1.2.3.4:65432';
    $query = curl_init('https://ip.oxylabs.io/location');
    curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($query, CURLOPT_PROXY, "http://$proxy");
    $output = curl_exec($query);
    curl_close($query);
    if ($output)
        echo $output;
?>
```

{% endtab %}

{% tab title="Python" %}

```python

    proxies={'http': 'http://1.2.3.4:65432',

print(response.text)
```

{% endtab %}
