Well, let's not focus on Bill's data. Frankly, I haven't seen any data
on this topic from any source that really convinces me that it
means much. All I know is that we have thousands of sites using
private address space, which completely falsifies any real data and
makes it impossible to attach any real meaning to concepts such as
"running out of addresses". My personal opinion is that we ran out
of addresses in practical terms around about when RFC 1597 was published.
