Have you run the numbers on the churn rate you would need to have any
probability getting aggregate-able blocks to come available in an
acceptable return-on-investment timetable for a commercial entity to be
willing to operate that kind of business model?
I work for an organization that received what will be its last
allocation of IPv4 addresses almost 19 years ago, it is only two days
away. We have been actively recycling out of our 5 /16 blocks for more
than 10 years. I can tell you, even in a much smaller address space
and with the ability to actually sometimes force readdressing,
re-aggregating blocks is extremely hard to do.
I find it extremely hard to believe there is a viable business model for
a commercial entity to make this happen at Internet scale, especially
with the realistic churn rates most people expect to see. There isn't
going to be enough additional value created by aggregating blocks to
justify the loss of potential revenue from holding on to the blocks too
long. Yes, it will happen, but not reliably enough to make a business
model out of it.
Additionally, the costs of disaggregation are too dispersed to find a
way to capture any of the potential Internet-wide cost savings from
aggregating blocks. So, I don't see how the economics of a business
model based on aggregation of blocks would work. Maybe, I'm missing
