Hi @taschmidt. No expert or docker employee. Only Docker for Windows beta user. The 10.0.75.2 is the IP the Hyper-V Manager is asigning to the VM that host the docker engine as you can see here:

If I run the following command on the VM (Using the Debug Console) I could see a process listening:
Hope that it could be helpful for you!
