[address-policy-wg] PI for IPv6 == PI for IPv4?

Hi Martin,

These numbers give me a different interpretation:

PI address space creates very scattered allocation as 16340 PI assignments
just covers 3,5% of the RIPE allocated address space. This is the point, is
n't it?

BTW, the 3,5% is not mentionned on the slides... but it was included in the
letter of Alex.

Second point: if ALL IPv4 PI holder would request IPv6 PI then you might
expect another 17K prefixes in the routing table just from the RIPE Region!
And this is just the start!

Thanks,
