Mit

  sock = socket.create_connection(('flupp.belwue.de',591))

bekomme ich einen tcp Link. Das funktioniert.

In der Doku steht dazu:

https://docs.python.org/3/library/socket.html

  Connect to a TCP service listening on the Internet address (a 2-tuple
  (host, port)), and return the socket object. This is a higher-level
  function than socket.connect(): if host is a non-numeric hostname, it
  will try to resolve it for both AF_INET and AF_INET6, and then try to
  connect to all possible addresses in turn until a connection succeeds.


flupp.belwue.de hat sowohl ipv4 als auch ipv6 Adresse. 
Welche wird genommen und warum?
