What is Administered port exclusions in windows 10?

问题

I have hyper-v enabled in windows 10. When I check the excluded ports, I get:

C:\> netsh interface ipv4 show excludedportrange protocol=tcp

Protocol tcp Port Exclusion Ranges

Start Port    End Port
----------    --------
      5357        5357
      9800        9800
      9801        9801
     49671       49770
     49871       49970
     50000       50059     *
     61117       61216
     61220       61319
     61902       62001

* - Administered port exclusions.

Why Hyper-V reserves these ports?

How Administered port exclusions ( ie, range 50000-50059 ) differ from other port exclusions?

For example, when i tried to ping to all these ports using a net.Listen() in golang, all ports except 50000-50059 returns error:

listen tcp 127.0.0.1:9801: bind: An attempt was made to access a socket in a way forbidden by its access permissions.
