ipconfig uses GetAdaptersAddresses(), which does include the loopback interface on Windows.
No problem with the ipconfig showing the loopback interface. I only added the ipconfig info to show that the loopback is considered an ethernet interface. Which might be the issue in the first place - it's not being skipped because wine sees it as ethernet and not loopback.
