Hello, I know that it is not for this GM meeting but let us consider different approach to the charging scheme. IPv4 is dead and any charging scheme based on IPv4 will only extends its agony. The new model should be based on IPv6 with highest price being paid by LIR without IPv6 implemented to some extent. The criteria could be: - allocation of IPv6 space from RIPE - announcement of IPv6 prefix - DNS and revDNS implemented - assignement of IPv6 addresses to some End Users - accessibility of LIR Web Page via IPv6 This approach will clearly increase the speed of IPv6 popularity. Technically, it has been (or is being) done by RIPE to check maturity of a LIR with IPv6. This will also have an impact on LIR End Users if they are told that they could pay more if they did not move to IPv6. At the the end some thoughts on current category Model - the ratio of an price increase/decrease for highest and lowest category is certainly not a small step or evolutionary change for LIRs in high categories - All IPv4 allocations has been done with RIPE approval in accordance to relevant polices at that time. - Most IPv4 allocations has been done in times when such thing as NAT did not exist.
