# 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 %}

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.decisionrules.io/doc/integrations/flow-integrations/ip-allowlisting.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
