socket.gaierror: [Errno -9] Address family for hostname not supported

Additional context

In socketserver.py line 439 we have an explicit bind to a legacy socket:

address_family = socket.AF_INET

changing this to AF_INET6 is enough to make it support explicit bindings to ipv6 addresses.

It also by default only tries to bind to the legacy any address in examples/smbserver.py line 43:

parser.add_argument('-ip', '--interface-address', action='store', default='0.0.0.0', help='ip address of listening interface')

Changing the default to :: fixes it.
