Hi Alex,

Thank you for these numbers. I think they are very useful.

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.
