sorry, many many many thousands of sites. for example, I would fairly
guess these days that 75% of sites use private address space. I would say
that 90% of the networks I've seen at our clients sites are using private
address space.
I would say that now, a lot of global ipv4 address space is used mostly for
the outside interfaces of sites: i.e. firewall external address,
web/smtp/... external servers.
