# Flood Contorl

The [Flood Control](https://www.drupal.org/project/flood_control) module provides a simple interface to configure hidden flood control options and provides the ability to remove IP addresses and user IDs from the flood table.

The **Flood Control** module is installed and enabled in Varbase by default, site admins are given access to the Flood Unblock table where the list of blocked IP addresses and user IDs can be seen.

### Unblocking Blocked Users and IPs

The **Flood Unblock** table can be accessed by navigating to **Administration** \ **People \\** ***Flood Unblock***.

The table shows the blocked users with other information like the timestamp of the failed login.

## 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://docs.varbase.vardot.com/9.0.x/developers/configuring-a-varbase-site/security-features/flood-contorl.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.
