This is probably not appropriate in here but I have to ask <WHY>

Is this a work-around or is it the correct way to do things, It just
seems a bit strange cause your class A/B/C hasn't changed so I would
have thought that the netmask would be the same for all addresses. 

I know a ffffffff netmask works as I am using it myself but I just
wondered.....
