Are the fees for an IPv6 allocation different to those for IPv4?
No. RIPE NCC members are charged an annual fee based on the services that the member receives according to the RIPE NCC Charging Scheme 2013.
There is no distinction made between those services related to IPv4 address allocation and those related to IPv6 address allocation. However, the number of addresses that a new member receives as the default minimum differs between IPv4 and IPv6 allocations.
Currently, a /32 IPv6 allocation (65,536 subnets each the size of a /48) scores the same in a member’s billing score as a /21 IPv4 Provider Aggregatable (PA) allocation (2,048 IPv4 addresses) or a /24 IPv4 Provider Independent (PI) assignment (256 IPv4 addresses).
