[New-bugs-announce] [issue36382] socket.getfqdn() returns domain "mshome.net"

[Markus]

New submission from Markus <markus.kramer at posteo.de>:

In a corporate network, `wmic computersystem get domain` returns the correct domain.

On some clients, the Python query "socket.getfqdn()" returns the wrong domain, namely "mshome.net"

>>> import socket
>>> socket.getfqdn()
'*****.mshome.net'

I have only found only very old nominations of that domain.

Problems persists after reboot.

Tried versions 
Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit (AMD64)] on win32
Python 3.7.2 (tags/v3.7.2:9a3ffc0492, Dec 23 2018, 22:20:52) [MSC v.1916 32 bit (Intel)] on win32

Currently, I suspect this is a DHCP configuration problem.
