You asked for a cross-platform solution; there probably isn't one.

The code below works on Unix and MacOS X.
If you can find code that works on Windows, you can cobble together
somthing that will work on most platforms.

dns_ips = []

for line in file('/etc/resolv.conf', 'r'):
     columns = line.split()
     if columns[0] == 'nameserver':

print dns_ips

Hope this help,
