I know one can turn on IPv6 along side IPv4 and gradually move stuff across to supporting
both IPv4 and IPv6.  I know that HTTP, SMTP and DNS servers have supported IPv6 for over
2 decades.  DHCP servers have supported IPv6 nearly as long.  I know firewalls have supported
IPv6 for over 2 decades now.  I know Windows has supported IPv6 since Windows XP. I know Apple,
Oracle (Sun), VMS, Linux, … have supported IPv6 as long if not longer.  I know turning on IPv6
doesn’t mean turning off IPv4.  Most CDN’s support IPv6 these days as well and you don’t have
to be running IPv6 in house to project a IPv6 presence on the net.  Routers have supported IPv6
for decades as well though not at the $50 mark until recently.

Turning on IPv6 isn’t hard even if most it the plant isn’t using it.  The front office can
definitely use it just like homes use it today.  Getting to the state where you are ready
to go IPv6-only is hard as it requires every piece of equipment to support IPv6, but don’t
confuse the two.

> When it comes down to making a decision about whether to implement IPv6, the decision is usually "build vs. buy" - "build" a new network, new server infrastructure, etc., vs. "buy" more IPv4 addresses. On residential networks, they can "build" at a sufficient scale to be cheaper than "buying". On enterprise networks, the "buy" option is usually cheaper (and far less risky to the revenue-generating portions of the business).

In many cases it is just enable.
