Is the "IPAddressRange.dll" in a deploy target folder, as well as your MVC app's DLL files, on that Windows Server 2016 Standard machine?

And is the "IPAddressRange.dll" file not broken? (The file size of "IPAddressRange.dll" should be 22.5 KB, and it should be able to show its file property from Windows Explorer.)
