It would be interesting to know how much of this space is really used
for something more or less permanent, and how much is just random
noise. For instance, I do a training course where people need to
configure routers, and I use addresses out of 96.0.0.0/8 for that,
because it has to be clear that we're talking about real addresses and
not RFC 1918 stuff. Although this doesn't interact with the real
internet, often, people end up having real addresses and also
96.0.0.0/8 addresses on their laptops so they probably generate some
DNS queries for the 96 range.
Would it be useful for IANA to publish the order in which they're
going to allocate /8s? That way, it's easier for people to plan
getting out of the way of real deployment in time.
