I am not as that is the reality on the ground at least from my experience

Yes such a study would come in handy as it would paint the exact picture I
was referring too.

Meanwhile there is the visual outlook.

Not so fast. We have less motivated  net engineers out there who are not
motivated at the moment to do it.

That IPv4 protocol is still kicking and flying and yeah they can still NAT
and get things rolling fast.

Dont forget almost all the Telecoms in this continent have at least some
IPv6 prefix seated with them and yet my 3G/4G smart phone still still gets
an RFC1918 address every time I get some data bundle fire-up.

Obviously but not so fast. Those internal services like DNS and WWW seat
behind some Firewalls that either dont support IPv6 or doing v6 could
result into some buggy scenarios. No one will risk that.

Secondly, those internal services dont normally need a lot of address space
:-). So a single /24 IPv4 could be allocated to some services and couple
with some NAT Port fowarding behind some Firewall and all is rossy.  So
IPv6 in this case becomes less of a priority.

Do you think I have not tried. I have and like I said, i will leave it to
the competition to be the motivation some day.

More like hands of my network :-)...

Well we do it others are doing it and that is how we will get the ball

I remember that talk as I was there but even in .za itself, the stats are
like sad but promising.

Ofcourse and as it stands, some are at least firing the protocol up on the
boarder routers and at most announcing to their ISPs.
