Currently my IPS provides IPv6, but I set up my firewall in the access router of my home LAN to block all IPv6 in both directions. - I don't want to have a permanent global unchanged ipv6 as in id of my traffic. - IPv6 privacy extensions would change that but then I can not reach my two devices I do want to reach from outside anymore as my access router only supports DynDNS for its own address and no NAT in IPv6

And how exactly is your NATed ipv4 address better? This seems backwards.

It has barely hit 50% and it's already plateauing. This adoption rate is ridiculous despite basically all network interfaces supporting it. I thought I would see IPv6 take over in my lifetime as the default for platforms to build on but I can see I was wrong. Enterprise and commercial companies are literally going to hold back internet progress around 60 to 75 years because it's in their best interest to ensure users…

My German ISP supports it now, which was the limiting factor for me, and a new VPS I just bought also does, so finally I was able to create my first personal AAAA record. I am hoping that we're seeing a tipping point. Again.

NB: this is not "IPv6 traffic crosses the 50% mark" but "availability of IPv6 connectivity among Google users", which is a very important difference. This means roughly half of Google users have IPv6 capability, which does not 1:1 correspond how much traffic is actually transferred over IPv6, which is what this submission says in the title.

And still, in the year of our lord 2026, GitHub does not support IPv6. https://github.com/orgs/community/discussions/10539

Do we know any technical reason for this? Or are we left to think this is somehow a political thing?

You probably need a hefty security reimplementation if you want to add IPv6 to Github.

I wish EU make it mandatory at least for all ISP to make mandatory support for IPv6 by end of this decade. I think that would push the needle even globally.

IPv6 will never make it. Maybe IPv8 [0], which IPv6 should have actually looked like: > 1.1.1.1.1.1.1.1 [0] https://www.ietf.org/archive/id/draft-thain-ipv8-00.html

Why do people keep proposing alternatives to IPv6 that are no easier than IPv6 but still require the whole world to start the deployment over from 0%?

Tailscale have a great FAQ about IPv4 vs IPv6: https://tailscale.com/docs/reference/faq/ipv6 If you're not an expert in this area it's worth a read - I certainly learned a few things!

That was excellent, thanks for recommending it. I particularly liked how it's a pretty factual FAQ, not particularly cheerleading for IPv6 nor saying "IPv6 is a failure, give up on it".

GitHub should absolutely support IPv6, but until then... transip.eu provide IPv6 addresses which transparently proxy to github.com: https://www.transip.eu/knowledgebase/5277-using-transip-gith... You'll need to update your DNS server to include those as AAAA records. Do providers like NextDNS or RethinkDNS allow these sorts of overrides?

>The Github IPv6 Proxy can only be used for traffic to Github using a VPS from TransIP which uses IPv6.

Router has a DynDNS function. I am using a reverse proxy for multiple services, but this only sets up router IP and IPv4 NAT port forwarding to the reverse proxy.

So what would be the correct setup with IPv6 when using privacy extensions?

I don't see any benefit in allowing IPv6 traffic or using IPv6, but a couple of new problems coming up with it.

Earlier quoted context omitted.

I recommend going through Hurricane Electric's multiple-choice tests. It's not exactly a how-to guide or course, but it'll mention all of the terms and technologies you need to look up to get things right. They'll even send you a free T-shirt if you make it through all of them. The most difficult parts for a homelab in my experience is getting Docker to play nicely. All of the other stuff sort of just works these day…

Where do I find that? https://www.ipv6.he.net/ has an invalid certificate and is the first result on Google.

Their www sub-subdomain is broken it seems.

https://ipv6.he.net/certification/ has instructions on how to get started.
