yep.
Interesting. So at the moment, it looks like between 30%-40% (i.e. from (393+851)/4050 to (339+393+851)/4050) of the ERX address space is arguably abandoned
from a measurement point of view 'arguably' may be the most important word in that sentence
what I said was: "it looks like between 30%-40% of the ERX address space is arguably abandoned from the point of view of RIPE-DB maintainership - although obviously not necessarily from other points of view". I'm certainly not saying that the address space is unused.
unfortunately we have never come up with a method to classify space rigorously. hard problem. and i am not optimistic. look at the recent noise about the uk gov /8 that looked unmaintained.
it was reasonably well known that this /8 was used internally within the UK's public sector networks. The only surprising thing about that noise was that it happened at all, but I guess we all have a special love for public display of moral outrage when it comes to bureaucracies. I agree that classification is difficult, but I'd like to play around with the data and see whether it throws up anything interesting. Nick
