Checking refusal of a network connection

I would expect that the IPv4 address from such a connection attempt
would be automatically converted to a IPv6 loopback address.

Unfortunately, the direct specification ?? socket-send_json_data.py --server_id ::1 ??
does not work at the moment because of the error message ?socket.gaierror: [Errno -9]
Address family for hostname not supported?.
