If LIR want to get more IPs and don't to want pay for it - he don't really need it.
He just want to get as much IPs as he can get for keeping it in store. And trying to get maximum IPs at minimal cost.
If you need IPs - you will pay for it. If you are not ready to pay for it - you don't need it.
That is how I see it.
I agree with this part. In my opinion:
LIR has a lot of IPs => LIR has a lot of customers or payed services => LIR earns more money
That’s why I think that all LIRs have to pay fixed rate for each /24 block. If they really need them they will pay for it. If they are not ready to pay for it - they don’t use their IPs efficiently or they have too many blocks.
I’m not writing about the price per /24 block. Just about general - and very simple - rule.
Kind regards,
