I doubt many of them wanted IPv4 either. They wanted Internet access,
or probably more specifically, email and world-wide-web access.

IPv4 and IPv6 are the 'whats' not the 'whys'.

If you walk up to somebody, even a technical manager, and say "we need
to deploy IPv6", their likely answer will be the question "why?" (or
"<sigh> Not this again."). You need to have an answer, and it needs to
be valid for the situation.

On the Internet, IPv6 is optional, because somebody can access
everything with just an IPv4 address.

The places where we are seeing it deployed by necessity are where it
may be becoming cheaper than IPv4 - in terms of either avoiding having
to buy IPv4 addresses (where IPv6 is available at both ends), avoiding
increasing CGN costs (I expect that explains Telstra's mobile role
out), or that it is simpler to have a pure IPv6 network internally,
and then translate to IPv4 for external IPv4-only clients at the edge,
which is what I've heard organisations like Facebook are starting to
do.

Because IPv4 CGN purchased capacity is inversely proportional to the
amount of IPv6 traffic an ISP carries, at some point an ISP will have
a strong incentive to encourage their customers to adopt IPv6 to lower
their IPv4 CGN capacity costs.

ISPs could create that incentive by making a dual IPv4/IPv6 stack
service cheaper than a single IPv4 stack service. The answer to the
"why" question above then becomes "because we get cheaper Internet
access."

Mark.
