# Duplicate IP protection

To prevent fraud, Private Panels will flag respondents who answer surveys from the same IP. When we find two surveys with the same IP, a little alert will pop up in the **Study Overview** page. This feature only works when [Who can take the screener](/private-panels/screeners/survey-status.md) setting is either **Anyone** or **Study Participants**.

## How to turn this off

You can also turn this setting off on the **Screener Settings** page.

## Find a survey response by IP

In a **Study**, click the **Quick Search** input field. You can either type out the entire **IP** (e.g. 123.1.2.3), or type **ip:XXX.XX.XX.XX** which has the ability to match multiple IPs (e.g. ip:127.1.2.3)

To find panelist profiles who share the same IP, [read this article](/private-panels/panel-management/track-panelist-ip-and-country.md).

**Note:** Private Panels was previously managed outside of Dscout, so you may see a different logo and URL in some places. If you have any questions, contact <support@dscout.com>.

# 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 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://help.dscout.com/private-panels/studies/duplicate-ip-protection.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.
