IP addresses that are used by App Connect Enterprise on IBM Cloud flows

In some circumstances, you might need to define inbound IP-based firewall rules to police the outbound connectivity from App Connect. You might also need to add App Connect IP addresses to an allowlist to police the inbound connectivity to App Connect.

IP addresses that are used for outbound connectivity from App Connect Enterprise on IBM Cloud flows

You might need to define inbound IP-based firewall rules when you use Toolkit-developed message flows in a BAR file in App Connect Enterprise on IBM Cloud® to connect to applications behind a firewall.

The IP addresses have the following values for outbound connectivity.

IP addresses that are used for inbound connectivity to App Connect Enterprise on IBM Cloud flows

You might need to add App Connect IP addresses to an allowlist in certain circumstances. For example, you might want a REST API to call Toolkit-developed message flows in a BAR file in App Connect Enterprise on IBM Cloud. Or you might want those flows to be called as callable flows by an on-premises flow. In these scenarios, you might need to add the App Connect IP addresses to an allowlist to permit the REST API or on-premises system to connect to App Connect Enterprise on IBM Cloud.

Note: A REST API calls these IP addresses to invoke a message flow in App Connect Enterprise on IBM Cloud. Similarly, an on-premises callable flow agent connects to these IP addresses.
The IP addresses are in the following range for inbound connectivity.
Location: Dallas or Sydney
169.46.120.184/29
169.48.246.216/29
169.61.8.192/29
Location: London
169.50.120.232/29
158.175.94.72/29
141.125.71.224/29
