# Start using ISP Proxies

{% step %}

### Set up a proxy user <a href="#h_33b47b08b9" id="h_33b47b08b9"></a>

To begin using Self-Service ISP Proxies, you'll need to set up a proxy user. Enter your chosen username and password, then click on Create proxy user. Be sure to save these credentials for future access. Proxy user credentials are your access to the IPs.
{% endstep %}

{% step %}

### Run a request <a href="#h_9c25408601" id="h_9c25408601"></a>

Once setup is complete, you can now create and execute your first [cURL request in a terminal](https://oxylabs.io/resources/integrations/terminal) or any other environment to test the ISP Proxies.\
​\
Send a query to <https://ip.oxylabs.io/location> using the command below, specifying port 8001 and your proxy credentials:

```
curl -x isp.oxylabs.io:8001 -U "user-USERNAME:PASSWORD" https://ip.oxylabs.io/location
```

{% endstep %}

{% step %}

### Get a response

Upon executing this command, the output will display the IP address with your request. When connecting through port `8001`, the same IP address assigned to this port will always be used. To switch to another IP, change the port to `8002`, `8003`, and so forth.
{% endstep %}
{% endstepper %}

### Get your proxy list

Access your proxy list in the dashboard by navigating to the My Products section, clicking on ISP Proxies, and selecting Proxy List.

### What's included in a proxy list? <a href="#h_e2437a8515" id="h_e2437a8515"></a>

| Entry point | A gateway for connecting to your proxies                    |
| ----------- | ----------------------------------------------------------- |
| Port        | A designated port to access a specific proxy from your list |
| Country     | The geographic location of your proxies                     |
| Assigned IP | A specific proxy IP assigned to the chosen port             |

### Location settings <a href="#h_d6defc9cf6" id="h_d6defc9cf6"></a>

ISP proxy network offers country [targeting](https://developers.oxylabs.io/proxies/isp-proxies/location-settings). Simply send a request to the port associated with the desired location's assigned IP:\
​

```
curl -x isp.oxylabs.io:8000 -U 'user-USERNAME:PASSWORD' https://ip.oxylabs.io/location
```

### Protocols <a href="#h_6066c07e7b" id="h_6066c07e7b"></a>

Self-Service ISP Proxies support HTTP, HTTPS, and SOCKS5 protocols. For instance, to connect through an HTTPS protocol, you must specify this in your request by adding https\:// to your entry point:\
​

```
curl -x https://isp.oxylabs.io:8000 -U user-USERNAME:PASSWORD https://ip.oxylabs.io/location
```

\
Make sure that the libraries or third-party tools you intend to use are compatible with HTTPS and SOCKS5 protocols.\
​

Here’s a code example with the SOCKS5 protocol:\
​

```
curl -x socks5h://user-USERNAME:PASSWORD@isp.oxylabs.io:8000 https://ip.oxylabs.io/location
```

### Response codes <a href="#h_2fed198008" id="h_2fed198008"></a>

When using ISP Proxies, you may receive response codes that indicate specific reasons for success or failure. Here are the most common ones:

| Response code | Error message                 | Description                                                                                                                                                                                                                                                                                                                                                                                             |
| ------------- | ----------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 400           | Bad Request                   | This error code can be returned by a proxy server if the request did not specify a host to connect to or if there was a general error in parsing the HTTP request. Ensure that the request is correctly formed, including the URL, and try again.                                                                                                                                                       |
| 407           | Proxy Authentication Required | This response indicates that the request lacks proxy authentication information or the username or password is invalid. Include the Proxy-Authorization header in your request, verify that your username and password are correct, and then try again.                                                                                                                                                 |
| 500           | Internal Server Error         | <p>The proxy server has encountered an internal error. Retry the request at a later time.<br>​</p>                                                                                                                                                                                                                                                                                                      |
| 502           | Bad Gateway                   | This response signifies that the IP assigned to your session ID is no longer available or there are no exit nodes meeting your specified parameters (e.g., city, ASN) at the given time. To resolve this issue, you can wait for one minute for the system to assign a new IP address to your session ID or switch to a new session ID (i.e., change the sessid parameter) to receive a new IP address. |
| 522           | Timeout                       | The proxy server did not get a response from the upstream server in time. Retry the request.                                                                                                                                                                                                                                                                                                            |
| 525           | No Exit Found                 | This custom HTTP status code means that the proxy could not find an exit node that satisfies the request. Adjust the request filter parameters or try again later.                                                                                                                                                                                                                                      |
