Is there a portable way to retrieve the local host subnet mask?

Hi all,

socket.gethostbyname_ex(socket.gethostname()) will return the list of IP 
addresses on a the local host.   I did not find any function that can be 
used to get the subnet mask and default gateway.

Under Win32, the Win32 IP helper API provides a  GetIpAddrTable() 
function that returns information that contain the subnet mask, but 
that's Win32 level, and is not portable.  Is there something available 
in the Python library for that purpose?
