You have my sympathies. Which gets you nothing but consolation.

That statement is too broad. Lots of companies are using IPv6 in prime
There may be some features with some bugs. I don’t know how we shake those
out if people don’t try those features and report the bugs.

IPv4 malfunctions, too. I haven’t seen anything to suggest that IPv6 is
less robust than IPv4. One does have to climb the learning curve and
develop support processes, but that’s true with anything, including IPv4.

So, CPE is buggy and sucks. I wish there was money to be made in
delivering quality CPE code.

You said above that you thought that CPE reliability is as good as IPv6.
There are quite a few models that work as well with IPv6 as IPv4. But not
But I didn’t ask you to be a developer here, I suggested you be a planner.
If you think you’ll want to provide your users with IPv6 within 5 years,
you should be providing IPv6-capable equipment now, even if you don’t
enable IPv6 yet. Otherwise, when you do start, you’ll have to make up the
And do report those bugs, or they’ll never get fixed!
