# Long Acting ISP Proxies

**Long Acting ISP Proxies** are fixed IP addresses that do not change. Unlike dynamic IP addresses, a long-term ISP address remains unchanged over time once assigned to a device (such as a computer, server, or router). Long-term ISP addresses are typically assigned by a network administrator or Internet Service Provider (ISP), and the IP address remains the same even after the device restarts or disconnects.

**Characteristics of Long Acting ISP Proxies:**

1. **Fixed and Unchanging**: Once assigned to a device, a long-term ISP address does not change automatically unless manually modified by a network administrator.
2. **Stability**: Because the address stays the same, Long Acting ISP Proxies are well-suited for services that require long-term, stable connectivity, such as website servers and mail servers.
3. **Easy to Manage**: For devices requiring remote access, a static IP simplifies network configuration and management. For example, you can use a long-term ISP proxy to set firewall rules or configure DNS resolution.
4. **Requires Configuration**: Long Acting ISP Proxies must be manually configured by a network administrator, and are typically obtained through an ISP or set up by an administrator within a local network.

## 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/en/proxies/long-acting-isp-proxies.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.
