But I still wonder about the why, at a deeper level, of what use (dial-up,
broadband, enterprise, personal, VoIP, ... ) these are being put to, something
that someone who has worked in or closely with one of the ISPs making use of the
larger allocations might have an insight into.
As I said, knowing more would enable better estimates of exhaustion, and would
inform discussions about such as IPv6 migration strategies.
