# IP Allowlisting

Integration Flow jobs run on dedicated infrastructure with fixed IP addresses, which are used for all outgoing connections. If your database or internal services restrict incoming traffic based on IP, these addresses must be explicitly allowed.

Make sure the required addresses are added to your allowlist before enabling the integration. The following IP addresses need to be included:

```
18.153.146.109
3.126.127.6
```

In CIDR notation:

```
18.153.146.109/32
3.126.127.6/32
```

{% hint style="info" %}
Decision Flow does not have fixed IPs — rule evaluation is distributed across dynamically scaled servers. IP whitelisting is therefore only supported for **Integration Flow**.
{% endhint %}

## 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.decisionrules.io/doc/integrations/flow-integrations/ip-allowlisting.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.
