Hi Alex, Thank you for these numbers. I think they are very useful. On 08/07/2009 7:43, "Alex Le Heux" <alexlh@ripe.net> wrote:

This suggests to me that if the default allocation from a reserved prefix is a /22, as suggested earlier, then we should assume that there will be at least an extra 300-400 prefixes used per year just from people who will request PI and maybe add some more onto that from people who would have been happy with a PA assignment but won't be able to get it. I think reserving a /10 to be cut into /22s would underestimate demand for the space. I doubt it would last anywhere near five years. We should probably consider whether we reserve more space or divide whatever we reserve into longer prefixes, maybe /24s. Regards, Leo Vegoda
