Your story is exactly why experienced managers will not touch v6.
At present this is still probably sensible. We see a bit over 20% of traffic
over v6 (not all our content is v6 enabled, some of our customers are
'experienced managers' although to some large eyeball ISPs we see over
50% of the traffic flowing as IPv6.
In practical terms, the only thing wrong with IPv4 is the scarcity of
addresses and for a business that's not an issue - you can just buy them
as they don't tend to need very many addreses. Talktalk has roughly 7m
addresses and a market cap of about £1bn - so there's a pretty hard
upper limit on IP address prices of £140 each at present, and that's
well within budget for a business that needs only 256.
(Yes I am suggesting at some point it'll be worth asset stripping ISPs
to obtain their addrsess space, not least because I've bought two where
the purchase price was lower than the present value of the IP space).
Of course an experienced IT managed should also be looking to the
future, how well do your services work behind NAT and CGNAT and do you
get better service if you support v6 to the end user? How many of the
ocntent sources you access are looking at their traffic graphs and
seeing that V6 is becoming the dominant protocol (especially mobile
focussed applications) so they'll need to offer v6 to mobile devices in
the office? Nothing is going to stop working over v4 any time soon, but
experienced IT manages have long had policies forbidding Apple
devices and using your own dvice on the corporate network which last until
the CEOs daughter on work experience discovers her iPhone game doesn't
work properly.
Things that IPv6 internally protects you from
- running out of RFC1918 space if your organisation gets big
- addgress overlap if you acquire someone / are acquired
- IP address costs if you can run your own things v6 only
I often wonder how you present the business case for never becoming huge
and never being acquired to the shareholders.
