On linux, look somewhere in the /proc

On windows there's some WINAPI for sure, but it could be PITA to go
through all the structures. Or try WMI (through Win32OLE) -- have look
at msdn.

It depends on your needs, but parsing ipconfig is the easiest way (be
sure to take care of localisation, we had problems when we moved from
english to, say italian windows.)

You can guess the netmask from the address class, but most probably
that won't work.
