I am looking for some information around IP addresses or FQDN's used by Document Routing Agent when installed on print servers with limited internet access. This is to allow configure the firewall on print server and allow the Document Routing agent traffic. 

I came across below thread https://github.com/MicrosoftDocs/dynamics-365-unified-operations-public/issues/755 but it did not has complete details. 

Can someone help with this information. Shall we whitelist all IP address of the Azure region where F&O is hosted on the print server as F&O might be communicating to DRA using one of those IP addresses mentioned at the link https://www.microsoft.com/en-us/download/details.aspx?id=56519

Thanks in advance.
