The requirement in the current policy (ripe-733) [1] that “After one year the utilisation of the new assignment must be at least 50%, unless special circumstances are defined" is implemented the way Marco previously explained: the 50% utilisation refers to an estimated projection, which must be supported by the documentation provided by the IXP when requesting an assignment larger than the minimum size. This requirement was first introduced in the ripe-604 [2] policy document, after the approval of proposal 2013-03 [3], to maintain the need evaluation for IXP assignments. The RIPE NCC Impact Analysis [4] on proposal 2013-03 was: “It is the RIPE NCC’s understanding that Internet Exchange Point assignments larger than /24 would be based on documented calculations that allow the utilisation to be estimated one year after the date of assignment. This utilisation should be at least 50% of the assignment. “
Hi, I want to also point out here that the «50% after one year» requirement as well as the «special circumstances» exception were not novel concepts first introduced by 2013-03, they were simply moved (and slightly simplified) from the general section of the policy into the IXP-specific section, as the need evaluation was being removed from the former. To be clear, it was our (the 2013-03 authors) intention to leave these mechanisms essentially as-is for IXP assignments specifically. The old pre-2013-03 policy (which covered both IXP and non-IXP assignments) read as as follows: «6.3 Utilisation Rates Assignments' immediate utilisation should be at least 25% of the assigned space. After one year, this should be at least 50% of the space unless special circumstances are defined.» See https://www.ripe.net/publications/docs/ripe-599 I have not attempted to figure out exactly when this language was introduced, but I suspect it has been around for a long time.
