Why do the fees so fundamentally fail to reflect the amount of resources held? (Compare, for example, with ARIN: https://www.arin.net/resources/fees/fee_schedule/)
Why should a small three-person ISP that becomes an LIR today pay the same as an entity that sells or leases IPv4 space it managed to accumulate (often in rather questionable ways) for millions of euros per year? Why should the largest operators in Europe, holding millions of IP addresses, pay the same as well?
