It should be obvious by now that much of the world doesn't want to let go of IPv4. That despite years of advocacy from proponents of IPv6
explaining how it solves various problems with the old standard. While the last unassigned blocks of IP addresses in Europe
and other places were handed out a few years ago, the allocation process continues. Address blocks previously assigned to one place that aren't well utilized can be reclaimed and re-assigned elsewhere. It's possible that IPv4 will never actually disappear completely from the Internet, based on how this so-called transition is going.
