ip address and network

[Mike C. Fletcher]

You could use something like:
    import struct,socket
    struct.unpack( '>I', socket.inet_aton( '193.108.240.17' ))[0]

to get the IP addresses as Python long integers, then do something like:

    (addr & (~mask)) == (network & (~mask))

There's more efficient ways I'm sure, but I don't have time to play too 
much today :) . 

Have fun,
Mike
