# Proxy usage

#### Proxy Configuration

**Format:** `user:pass@ip:port`

The proxy provider you use has a major impact on the tool's performance. We recommend using one of the supported providers listed directly in the tool, as they have been tested and verified to work reliably.

* **Vital Proxies** offers the best overall performance and success rates. It's the recommended choice if you don't mind spending a little more and know you'll be using solvers regularly.
* **DataImpulse** is the better option if you're on a budget. It performs well for the price, but overall reliability and success rates are lower than Vital Proxies.

Using an untested third-party provider may result in reduced performance, increased failures, or compatibility issues.

**Residential proxies are required. Do not purchase datacenter proxies under any circumstances.**

Your proxy configuration is just as important as the provider itself. Configure your proxies exactly as shown in the tool. Some providers may use slightly different names for the same settings—if so, select the closest equivalent to the recommended configuration.

## 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://g4tools.gitbook.io/g4tools/proxy-usage.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.
