Bug/Help Needed: Private Enpoint Exposes only one NIC IP address

[mehighlow]

Describe the bug

Private Endpoint Integration for CosmosDB exposes only one NIC IP address. However, a Private Endpoint might create more than one NIC + IP address. Automation can be leveraged to create just one DNS record, although both IP addresses remain valid for establishing connections.

The issue arises because the CosmosDB client (Azure SDK for .NET), by default, has the LimitToEndpointProperty set to false. This configuration instructs the SDK to automatically discover write and read regions and use them when the configured application region is unavailable. In my case, the application opted to use the regional FQDN, even though the endpoint connection was configured as global. This behavior can be addressed by setting the LimitToEndpointProperty to true, but this adjustment requires knowing what to look for.

Azure Service Operator Version: 2.9.0

Expected behavior

Both regional and global ip addresses are exposed

To Reproduce

Deploy CosmosDB with Private Endpoint integration. Use the Azure SDK for .NET to establish a connection to the database with default settings. Observe that the client selects the regional endpoint, even though the supplied database FQDN is global.
