# 长效静态 ISP 如何续费？

SK5Data 长效静态 ISP 支持在套餐有效期内续费。

**操作步骤：**

1. 进入 **长效静态 ISP → 代理列表**。
2. 找到需要续费的 IP，点击 **续费**。
3. 确认续费信息并完成支付。

续费成功后，IP 的有效期将在原到期时间基础上顺延 **30 天**。

对于需要同时续费多个 IP 的用户，可以勾选相应 IP，使用 **批量续费** 功能。

正常情况下，在有效期内完成续费后，原 IP 可以继续使用，无需重新配置新的 IP 地址。

**建议在 IP 到期前完成续费，以避免代理连接中断。**

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://doc.sk5data.com/doc/zh/faq/tong-yong-wen-ti/chang-xiao-jing-tai-isp-ru-he-xu-fei.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.
