A multinational company should look at the costs of not having an
aggressive program of introducing mechanisms that make it easy to
renumber. Also, in an Internet economy, any organization that takes
years to do anything has the future prospects of a brontosaurus.
Consider a scenario such as your ISPs being audited to see that they
are assigning address space efficiently. In the process of the
audit, the address registry learns that you have a registered /16
that you are not advertising, but want more registered space from
your providers' allocations.
As address space becomes more tight, I can picture the ISPs being
told they can't consider your requirements as part of their address
justification. Not necessarily a likely scenario today, but not
beyond the bounds of plausibility.
I apologize if I'm seeming sharp, which might be due either to my
broken ankle or the drugs I'm taking for it. But I get very, very
tired of companies that want to play in the public Internet, but find
it too inconvenient to be good Internet citizens with respect to
address utilization and impact on global routing. Don't get me wrong;
some very large networking companies are in this category. Doesn't
make me less tired of it.
Don't even begin to get me started on new.net.
