Ok, thanks for the reply Jason. I think the example I gave was confusing me, sometimes these books don't use the best example.
In the example I gave then am I to assume that this is NOT conserving IP addresses but simply an efficient way of reducing entries in routing tables? The examples you gave demonstrate this more but in the one I put forward (pulling the bits to the left) 8 Class C networks have been given away whichever way you look at it. So this company could have been allocated either: 200.100.48.0/24 200.100.49.0/24 thru to 200.100.55.0/24 Or they could be allocated 200.100.48.0/21, it's the same thing but just one entry is needed on their 'border' router and others with routes to their network?
