Describe the bug

The MRTK Build Window (Deploy Options) defaults to connecting to a HoloLens over 127.0.0.1. As per the MRTK documentation ( See Using the Windows Device Portal ), IpOverUsb is no longer recommended. The link/button "Open Device Portal" is now broken since http://127.0.0.1:10080/ does not work.

However, the Test Connection button does confirm that it is able to connect to my HL2.

To reproduce

1. Set up a new project with MRTK.
2. Navigate to Mixed Reality > Toolkit > Utilities > Build Window > Deploy Options

Expected behavior

The IP used for a Local connection should be 169.254.x.x .
Maybe the best solution is to have inputs for the last two values in the IP?
