This.

IPv6+NAT creates a lot of the issues that IPv4+NAT does, so why bother
deploying IPv6 when you've already got the equivalent via IPv4 today?


People need to understand why enterprises go to the expense of deploying
technologies.

Technology is a means to an end, not the end itself. Technology in business
either saves money or makes money for the business.

Enterprises in the 1990s didn't really deploy IPv4, they deployed global
email and WWW access. Deploying IPv4 was the means to reaching those ends,
because IPv4 underpinned them.


So the questions to think about in the context of businesses and
enterprises and IPv6 are:

- What business problem does or can IPv6 solve better than existing IPv4?

- IPv6 is the technology means to an end, so what is or are the ends that
are of value to a business, where IPv6 is the better underpinning
technology than IPv4 to reach those ends?

- How can deploying IPv6 save or make money for a business?

Regards,
Mark.
