The Windows binary build from www.python.org appears 
to be missing IPv6 support.

The IP configuration in my Windows XP + Service Pack 
1:
C:\Documents and Settings\zolty>ipconfig
Configuración IP de Windows
Adaptador Ethernet Conexión de área local          :
        Sufijo de conexión específica DNS :
        Dirección IP. . . . . . . . . . . : 192.168.0.2

Here's an example of a socket with ipv6 protocol/family:

Python 2.2.1 (#34, Apr  9 2002, 19:34:33) [MSC 32 bit 
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more 
information.
>>> import socket
>>> a=socket.socket
(socket.AF_INET6,socket.SOCK_STREAM)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'module' object has no 
attribute 'AF_INET6'

While your observation is correct, I fail to see the
importance of this problem.

Please understand that what you want is unimplementable with
MSVC6, since it does not provide the necessary header files
and library routines.

IPv6 support is only available if you use CVS Python, and
VC.NET.

I have changed the group to Python 2.3; for Python 2.2, this
would be a new feature, and thus won't be fixed.

Since Python 2.3 is not build with VC.NET either, moving the
target release for this issue to Python 2.4.

Python 2.5 and newer support IPv6 on Windows.
