Chris , Thanks for the info...
Let me explain my requirement ....
My company has 3 upstream providers and we are serving more than 400
customers ..In that case we have to manage our upstream capacity... When
considering capacity managing normally we just transfer a  /24 from
 congested Up stream provider to non congested provider.
Issue we have is we don't know exactly the usage of a /24 subnet before
transfer.

I hope you get an idea about my requirement  :) :) :)
