{% hint style="info" %}
我们的客户支持团队全天候 24/7 可用——请通过 [**support@oxylabs.io**](mailto:support@oxylabs.io) 或通过我们的在线聊天 [**网站**](https://oxylabs.io/)。他们会协助您为您的账户启用 SOCKS5 协议。默认情况下，HTTP 协议已启用。
{% endhint %}

#### HTTP

我们的文档包含代码示例，展示如何使用 `HTTP` 协议。该协议受常见库和第三方软件支持。

#### **SOCKS5**

要使用 `SOCKS5` 协议，你需要添加 `socks5h` 在您的请求中，例如：

```
curl -x socks5h://1.2.3.4:1180 -U USERNAME:PASSWORD ip.oxylabs.io
```

#### 代理端口

代理端口的默认配置包括 `80` 和 `443`，这些标准端口旨在适配 `HTTP` 和 `HTTPS` 协议，如下表所示。要访问其他端口，需要进行合规性验证，请联系我们的 [**支持**](mailto:support@oxylabs.io).

| 协议      | 端口    |
| ------- | ----- |
| `HTTP`  | `80`  |
| `HTTPS` | `443` |

# Agent Instructions

## 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/cn/proxies/dedicated-isp-proxies/enterprise/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.
