Why MinimServer using different ipaddress for MinimServer UI and ohnet

[paultaylor]

Running MinimServer on a PC, could see it fine on a control point on same PC but had problem trying to play track on a renderer not on PC.

If use Ipconfig on PC it has a usual ipaddress 192.168.178.34 and also a vEthernet ipaddress 172.17.109.49

Code:

Windows IP Configuration

Ethernet adapter Ethernet:

   Connection-specific DNS Suffix  . : fritz.box
   Link-local IPv6 Address . . . . . : fe80::e441:5f88:7515:3253%9
   IPv4 Address. . . . . . . . . . . : 192.168.178.34
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.178.1

.....

Ethernet adapter vEthernet (Default Switch):

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::75e0:5371:3ca2:4d1c%26
   IPv4 Address. . . . . . . . . . . : 172.17.109.49
   Subnet Mask . . . . . . . . . . . : 255.255.255.240
   Default Gateway . . . . . . . . . :

Not clear what vEthernet is meant to be used for but whilst I could connect to MinimServer UI using 192.168.178.34:9790 the ohport was 172.17.109.49:9791 rather than 192.168.178.34:9791. I fixed the issue by setting ohnet.port on MinimServers System tab to 192.168.178.0

But my question is why did MinimServer decide to use two different ipadresses for UI and Upnp server port, doesnt seem a good default, and would it be better for MinimServer to always ignore the vEthernet option as it is only going to work if al components (renderer, control point, server) are on same computer
