Get the IP addresses used to access your FusionAuth Cloud instance.

> For the index of this section of the site, see [llms.txt](https://4002.18-224-161-104.sslip.io/docs/llms.txt)

Depending on your security posture, defense in depth requirements, and application architecture, you may need the IP addresses or hostnames of the instances in your FusionAuth Cloud deployment.

There are any number of reasons you might need this information, including:

*   Adding the values to the allow list for your SMTP service.
*   Punching a hole in a firewall to allow FusionAuth webhooks to be delivered.
*   Updating a network access control list to enable access to an on-premises LDAP directory with a connector.
*   Any other outbound connection from a FusionAuth deployment.

To get the IP addresses for your deployment, please [open a support ticket](https://account.fusionauth.io/account/support/). Include the name of the deployment for which you need the outbound IP addresses.

Caution

Provided IP addresses should not be used for HTTP requests such as API calls; they won't respond to such requests.

This information should be used only to allow outbound traffic from FusionAuth deployments through firewalls and other network control layers.

In addition to using these IP addresses, consider custom headers, TLS transport and client certificates to ensure that outbound traffic is appropriately secured.
