I strongly suggest putting some network numbers aside for this purpose.

We have recently received a number of requests from customers wanting IP network numbers which are never intended to be routed to the global Internet. consume a chunk of the provider's space. Also, how large should that block be to satisfy all requests for non-connected network numbers?

I would almost have suggested using a class-A net for this :-) except that I have found the lack of flexibilty and understanding (of subnetting rules and variable subnet masks) to be very prevelant in the 'industry'. Since the underlying and existing software seems to deal with class-C nets so much more nicely, can we allocate a class-[AB] and a chunk of class-C nets ? Explaining the concept of split-subnets to confused end users time and time again is pretty tiring... -vikas
