Currently there is no policy in ARIN that would do that short of the last /10, so, the line should change at 1/4 of the last /8. Owen On Feb 2, 2011, at 10:43 AM, Richard Barnes wrote:
Note that the ARIN, APNIC, and RIPE lines should all basically level out to asymptotes after they hit 1 /8 left, due to the "soft run out" policies in place [1][2][3]. Either that, or just consider arriving at 1 /8 left as depletion.
Geoff: How are your graphs dealing with these policies?

So in the interest of 'second opinions never hurt', and I just can't get my head around "APnic sitting at 3 /8's, burning 2.3 /8's in the last 2 months and the idea of a 50% probability that their exhaustion event occurs Aug. 2011", here are a couple other graphs to consider. http://www.tndh.net/~tony/ietf/IPv4-rir-pools.pdf http://www.tndh.net/~tony/ietf/IPv4-rir-pools-zoom.pdf
Tony Two things:
1) you'll get better uptake of your graph if it's visible as a simple image, rather than requiring a PDF download. :/ Not wishing to advertise google but
http://docs.google.com/viewer?url=http://www.tndh.net/~tony/ietf/IPv4- rir-pools.pdf and http://docs.google.com/viewer?url=http://www.tndh.net/~tony/ietf/IPv4- rir-pools-zoom.pdf
works for me without needing to download a pdf viewer
For some reason that viewer didn't work here, so I added jpg's to the site. http://www.tndh.net/~tony/ietf/IPv4-rir-pools.jpg http://www.tndh.net/~tony/ietf/IPv4-rir-pools-zoom.jpg

2) labelling the Y axis would help; I'm not sure what the scale of 1-8 represents, unless it's perhaps the number of slices of pizza consumed per staff member per address allocation request?
I thought about leaving it off completely, but figured I would be asked for scale. It is /8's remaining until they drop into their 'last allocation' policy. I will see if I can figure out how to fit that into something readable.
But I do agree with what seems to be your driving message, which is that Geoff could potentially be considered "optimistic". ^_^;
Geoff has always been the optimist ... ;0
