Blockers to IPv6 Adoption

#12For me, there is just one thing that prevents me from switching completely to IPv6: Github.
Really? Each and every other thing you need already does IPv6?

#13Performance? How exactly is ipv6 more performing? It even has bigger headers. Why would ipv6 be more reliable than ipv4? I’d say it’s the opposite: many times I’ve found websites with AAAA registers that pointed to a dead server. I mean, if you’re going to blame cgn for your problems, let’s steep to your level. Analytics? Forensics? So you’re telling me ipv6 destroys my privacy. How is that a pro argument?
I noticed that enabling IPv6 in the JVM makes many operations slower. Has anyone else noticed this?

#14I deployed a dual ipv4 + ipv6 stack on my home lan a few years ago. I got myself a /48 from hurricane electric, and did everything like it's in the book: SLAAC for subnets, fixed addresses on servers, every device had a public ipv6 and the firewall allowed or denied stuff. Everything worked as it should work. One day something stopped working on the he tunnel, and as I was about to debug what went wrong, I just asked myself "Why am I doing this? My ISP has no ipv6, every site I visit has an ipv4 address, why am I keeping all this ipv6 stuff on? I don't need it. It's just useless work". And so I reverted everything to ipv4 and I am happy since. Less work for me.
I see NO reason to deploy ipv6 at the moment. I don't see it for home lans, I don't see it for my workplace, I don't see it for bigger enterprises.
But you can have a gazillion IPs with ipv6!! Yeah, so what?

#16I've enabled ipv6 on my ubuntu server recently and it was 100x slower. The only solution I found is to go back to ipv4: https://askubuntu.com/questions/759524/problem-with-ipv6-sud...
Re: Blockers to IPv6 Adoption
#17Comcast is my biggest blocker to IPv6 adoption. I maintain a static v4 block with them, they tell me I have to give that up if I want a v6 block. Until I give up v4, v6 works on my network right up to the Comcast modem, and is promptly dropped on the floor. Regrettably, that is 'no bueno' for a multitude of reasons. :-(

#18well K8s can't be run in Dual Stack, which is a major Pita.
Also most Clouds (especially Gcloud) mostly work on the IPv4 level.

Was all IPv6 traffic slower or just this one apparently misconfigured host?
If the former I'd image this is a kernel bug and has nothing to do with any Ubuntu servers.
Re: Blockers to IPv6 Adoption
#20What we should take away from the IPv6 debacle is a fine lesson in hubris.
I was hanging out in the IPv6 mailing lists at the time the various solutions were being debated.
The prevailing attitude was "the Internet is about to die from routing overload without IPv6, so we can stick whatever complexity we want inside it, and they will have no choice but to accept it."
Except that new router hardware and new incremental software improvements came out, and the enormous complexity of the "boil the ocean" redesign inherent in IPv6 was rightly regarded as completely unnecessary.
If the IETF had simply made IPV6 "ipv4 with longer addresses", (and there was a proposal to do just that), implementations and deployment would have been dramatically simpler and would have stood a real chance of succeeding.
Instead we have this baroque construction, which I _still_ have to explicitly disable in my work environment because various bits of supposedly IPV6 software don't play nice together.
