Can't disagree with anything there
IPv6 works (well, assuming you have no vendor bugs and a helpful ISP to hand), and does solve all the technical hurdles it was meant to.
The problem is it very much looks like it was developed in a lab by very clever people under perfect network conditions, with scant regard to how people do things in the real world due to a lack of knowledge, budget constraints, or complete apathy.
Compared to the simpler, backwards compatible option of dropping a few extra octets onto IPv4 to solve the address shortage, it may be a case that IPv6 let perfect be the enemy of good.
No-one's arguing IPv6 won't eventually be the dominant protocol: We're too far down that road, and too much has been invested into it, and again, it does actually work and solve these issues. But until you *Have* to use it, you may as well plod on with IPv4 which can do everything you need it to, and let the bleeding edge companies (And server to server traffic) work out the kinks for you, then worry and spend on it when you need to.
I've tried on and off every few years to get a Dual Stack link to the outside world on my home network; every time, I got so far down that path before hitting a roadblock (Flaky ISP Support, router support, router bugs, Happy Eyeball issues), before stopping and seeing I'd be spending a lot of time and money to make things technically better, but not letting me do anything new, and shelving the attempt again.
Biting the hand that feeds IT
