When can I request an additional IPv4 allocation?
When approximately 80% of your existing IPv4 allocation is in use, you may request a one time /22 (1,024 IPv4 addresses) allocation, even if you can justify a larger allocation. This /22 allocation will only be made if you have already received an IPv6 allocation from an upstream LIR or the RIPE NCC.
Please note that you have to be a RIPE NCC member to receive the /22 IPv4 allocation.
