# 长效ISP代理

**长效ISP代理** 是一种固定的、不会改变的IP地址。与动态IP地址不同，长效ISP地址在分配给某个设备（如计算机、服务器或路由器）后，不会随着时间的推移而变化。长效ISP地址通常由网络管理员或互联网服务提供商（ISP）分配，并且该IP地址在设备重新启动或断开连接后仍然保持不变。

**长效ISP代理的特点：**

1. **固定不变**：一旦分配给某个设备，**长效ISP**地址不会自动更改，除非网络管理员手动修改。
2. **稳定性**：因为地址不变，**长效ISP代理**适用于需要长期稳定通信的服务，如网站服务器、邮件服务器等。
3. **易于管理**：对于需要远程访问的设备，静态IP可以简化网络配置和管理。比如，你可以使用**长效ISP代理**设置防火墙规则，或者设置域名解析。
4. **需要配置**：**长效ISP代理**需要网络管理员手动配置，并且通常需要通过 ISP 获取，或者在本地网络中由管理员设置。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.9http.com/dai-li/chang-xiao-isp-dai-li.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
