# Valid IP Addresses for Limio Services

To support your organisation's network security and monitoring, Limio provides the following IP addresses for key services. We recommend adding these IP addresses to your allow list (also known as an allowlist or trusted IP list) and using them to help identify unusual or unauthorised activity.

This article outlines the valid IP addresses used by Limio for delivering webhook events as well as setting the connection between Limio and Salesforce as explained in [Connect Limio and Salesforce](/integrations/populating-salesforce-data/connect-limio-salesforce.md). These are the only IP addresses that should be sending webhook traffic to your endpoints.

### Valid IP ranges used by Limio

| Service  | Region             | IP address       |
| -------- | ------------------ | ---------------- |
| Webhooks | Europe (EU)        | `18.184.42.235`  |
| Webhooks | North America (NA) | `54.205.175.178` |

These static IPs are used exclusively for outbound webhook traffic from Limio to customer-managed endpoints.

> ⚠️ **Important**: If you receive webhook traffic from any IP not listed above, it may not originate from Limio. Please investigate this activity promptly and contact Limio Support if needed.

### How to use these IPs

We recommend the following actions:

* ✅ Add the listed IP addresses to your **firewall or endpoint allow list**.
* 🔍 Use these IPs to **filter and monitor incoming traffic** in your observability tools.
* 🛑 Flag any webhook traffic **not** originating from these IPs for further inspection.
