# Protocols

ISP Proxies support HTTP, HTTPS, and SOCKS5 protocols. Learn how to configure these protocols for secure and versatile tasks.

### HTTP

Our documentation includes code examples showcasing how to connect to the proxies using `HTTP` protocol. The protocol is supported by common libraries and third-party software.

### HTTPS

You can also use the fully encrypted connection using `HTTPS` protocol for an extra layer of security. For that, you have to add ‘https\://’ to your proxy entry point. For example: `https://isp.oxylabs.io:8001`

<pre class="language-sh"><code class="lang-sh"><strong>curl -x https://isp.oxylabs.io:8000 -U user-USERNAME:PASSWORD https://ip.oxylabs.io/location 
</strong></code></pre>

### SOCKS5

Oxylabs ISP Proxies support both `TCP` and `UDP` connections.

For using `SOCKS5` protocol, you have to add `socks5h://` to your proxy entry point. For example: `socks5h://isp.oxylabs.io:8001`

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

{% hint style="info" %}
Note that some websites may identify a proxy IP when using the `SOCKS5` protocol. We highly suggest switching to an alternative protocol in such instances.

## 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/proxies/isp-proxies/protocols.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.
