Is it possible to obtain static IP addresses from the smapOne servers?

No, the servers of smapOne are hosted in Microsoft's Azure Cloud, which does not provide static IP addresses. Instead, the IP addresses or address ranges can be dynamically retrieved via a link provided by Microsoft. For relevant information regarding the IP ranges of smapOne servers, Microsoft offers a webpage (also available for automated retrieval). Please search for the entries AppService.GermanyWestCentral and AppService.GermanyNorth.
