# IP Addresses for Domain Scanning

Aikido uses dedicated IP addresses to perform scanning of your domains (DAST). To prevent connectivity issues, rate limiting, or security blocks, add these IPs to your firewall’s allowlist or other security software.  After this, rescan your domains to confirm connectivity.

{% hint style="warning" %}
To use 'Fetch OpenAPI by URL', you must also add the [Code & Container scanning IP addresses.](/~/revisions/SGhJfnCIOpxRjx1gC1k5/code-scanning/miscellaneous/allowing-ip-addresses-for-code-container-scanning.md)
{% endhint %}

**EU-based IP addresses:**

* 3.248.4.169
* 54.76.211.68
* 54.228.156.63
* 54.247.155.164
* 18.200.152.99
* 18.202.99.112
* 52.48.122.82
* 54.194.175.200

**US-based IP addresses**

* 98.85.190.95
* 52.204.144.1
* 44.209.56.130
* 18.210.114.117
* 35.168.38.209
* 35.173.56.162
* 54.227.161.94
* 44.209.154.183

**Optional IP addresses (used for troubleshooting with support):**

* 79.127.239.171

#### Request Headers

All requests from Aikido's scans include one of the following headers, which can also be used for allowlisting:

* `aikido-scan-agent/1.0`

## Third party provider instructions <a href="#third-party-provider-instructions" id="third-party-provider-instructions"></a>

For instructions on adding IP addresses to allowlists with third-party providers, refer to the following resources:

* [Cloudflare WAF](https://developers.cloudflare.com/waf/custom-rules/use-cases/allow-traffic-from-ips-in-allowlist/)
  * Cloudflare Turnstile does not support allowlisting specific client IP addresses. If you need to [bypass Turnstile for Aikido scanning traffic, you must do it in your application code.](https://developers.cloudflare.com/turnstile/tutorials/conditionally-enforcing-turnstile/) We recommend bypassing only when both conditions are true:
    1. The request originates from an Aikido IP range
    2. The request includes the `aikido` User Agent in headers as described above
* [Azure WAF](https://learn.microsoft.com/en-us/azure/web-application-firewall/ag/custom-waf-rules-overview)
* [AWS WAF](https://docs.aws.amazon.com/waf/latest/developerguide/waf-rule-statement-type-ipset-match.html).
  * For WAFs behind Application Load Balancers or CloudFront, your [WAF should check the last IP address in the `X-Forwarded-For` header](https://docs.aws.amazon.com/waf/latest/developerguide/waf-rule-statement-forwarded-ip-address.html).
* [Vercel WAF](https://vercel.com/docs/vercel-firewall/vercel-waf/custom-rules)
  * Use the ["bypass" action](https://vercel.com/docs/vercel-firewall/firewall-concepts#bypass) for trusted IPs

# 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.aikido.dev/~/revisions/SGhJfnCIOpxRjx1gC1k5/dast-surface-monitoring/allowing-ip-addresses-for-dast-surface-monitoring.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.
