On the contrary, denying this block is likely to _accelerate_ usage of what space remains, thereby penalizing the 'other users' whose interests you _claim_ to be protecting. If an ISP can't use a shared block, they'll go ask their RIR for a block - and given that they demonstrably have the need (lots of customers), they will get it. Multiply than by N providers. Again, denying this block is just an attempt to punish ISPs who aren't doing what you want - nothing else. There is _no_ good engineering reason to deny this request. >> Allocate, or don't allocate.

Don't you think any network that was going to do the second would have already decided that? The ones who are going to do CGN are going to do CGN - the only question is what block of address space they are going to use. Denying them a block is not going to stop CGN.
