Dear RIPE members and community, We have come across a question of correct interpretation for "utilization" wthin´the current "IPv6 Address Allocation and Assignment Policy" RIPE-738 document: 5.2.2. Applied HD-Ratio The HD-Ratio value of 0.94 is adopted as indicating an acceptable address utilisation for justifying the allocation of additional address space. Appendix A provides a table showing the number of assignments that are necessary to achieve an acceptable utilisation value for a given address block size. [...] 10. Appendix A: HD-Ratio The utilisation threshold T, expressed as a number of individual /56 prefixes to be allocated from IPv6 prefix P, can be calculated as: T = 2((56-P)*HD) Thus, the utilisation threshold for an LIR requesting subsequent allocation of IPv6 address block is specified as a function of the prefix size and target HD ratio. This utilisation refers to the use of /56s as an efficiency measurement unit, and does not refer to the utilisation of addresses within those End Sites. It is an address allocation utilisation ratio and not an address assignment utilisation ratio. [...] The two underlined sentences seem to contradict each other. For a correct interpretation and calculation of the HD-Ratio/Utilization-Threshold (T) for IPv6-subsequent block eligibility, what is now correct "allocation" or "assignment" ? In the LIR-Portal there is an %-indication for "my own resources" which soley refers to assignments within a specific block. Allocations seem not to be considered. What is the correct way to calculcate the utilization?
