Depending on your solution architecture, you may have combination of Infogix Cloud hosted products and local products. Network security may require an allow-list of IP addresses or DNS entries for outbound communication from the local instances to the Infogix Cloud instances.
This is particularly common for Data360 Govern instances where a local instance of Data360 Analyze is used for metadata extraction. A similar setup can exist with Infogix Controls or Data360 DQ+ hosted instances.
To build the allow-list, your IT or Security teams must use of the DNS entry of your specific Infogix Cloud hosted instance. The specific IP address and ranges would not be adequate as the Infogix Cloud hosted environments have dynamic failover nodes.
