For your own AS, your internal records should tell you how much space
you have assigned, and your own equipment should give an indication of
how much of each assignment is actually in use (how accurate this can
ever be is left as an exercise for the reader)

As of May this year, there are over 37k ASes in the routing system,
announcing over 360k prefixes. I never like to say that anything is
impossible, but this task (although interesting) would certainly be very
hard.

From the MAT perspective, I think that identifying used vs. unused
addresses is of notional interest, but I don't believe it's within the
means of the RIPE NCC to collect that data regionally, let alone globally.

The concept behind RIPEstat does fully support using third party
datasets (where permitted), and we'd be happy to add a plugin to expose
this if the dataset owner permitted.

On the topic of reassigning unused v4 space to needy LIRs, I'll point
you towards the Address Policy WG http://www.ripe.net/ripe/groups/wg/ap

Thanks for your suggestion, please keep these ideas flowing. If anyone
else has opinions on this topic, do please share.

Regards

Mark
