I am not sure if it is me on the article sounds like it was passed through an LLM. These days I see more and more content similar to how the chat GPT would generate and describe things

Everything is "seamless" with ChatGPT.

IPv6 is seamless, etc...

Indeed! Look at these formulations: "Respecting these governance frameworks is crucial to maintaining the open, collaborative model that underpins global Internet development and its technological evolution ... collaborative approaches that engage technical communities, promote open standards, and prioritise interoperability are essential... To overcome these challenges, a strategic approach combining economic and op…

I'm not convinced. I don't think this is gibberish.

My hunch is that AWS charging for v4 addresses will start applying pressure across a broad cross-section of businesses as they start asking why don’t they just use the free thing

Half of AWS services aren't even available from an IPv6 endpoint, it's a clusterfuck. I'm all for carrot and stick but they are making a giant mess of it. Source: https://docs.aws.amazon.com/vpc/latest/userguide/aws-ipv6-su... , see 'IPv6 only support' column.

Is that relevant? There's nothing wrong with having RFC1918 addresses and globally-routable IPv6 addresses assigned to your VPC.

Have the RFC1918 addresses accessing IPv4-only AWS resources and the globally-routable IPv6 addresses serving the world. Easy.

After all, the major cloud providers don't charge for RFC1918 addresses... they just charge for globally-routable IPv4 addresses.

> One key reason for this uneven progress is the extension of IPv4’s lifespan through interim technologies like Network Address Translation (NAT) and IPv4 address transfers.

they completely ignore the actual problem with IPv6 which is that they didn't just extend IPv4 in a straightforward manner. they could have made the address fields 64 bits and been done with it. but, oh no, they had to make it the protocol for the ages.

it's completely analogous to the failed Intel Itanium vs. AMD x64.

One of my pet hot takes is that IPv6 will never exceed ~60% adoption. NAT and SNI routing (aka virtual hosts at the TLS layer) solve most problems for most users fairly well.

I doubt it. People will just start setting up load balancers with SNI routing if cost becomes a problem.

It's a pretty backwards way to build your network. You pay all the costs and gain none of the benefits.

Only if one delves.

I can see how you might suspect that, but I got a different read from it. The constant references to the topic as the "IPv6 Cat" struck me as another in the long tradition of authors who became too attached to a clumsy and ineffective analogy they thought was good enough™ and banged it like a drum. That strikes me as an all-too-human thing to do (especially since I've been guilty of it myself before) rather than an AI artifact. I enjoyed the piece nevertheless, and I agree with its premise that market forces are not enough to continue the trend of IPv6 penetration growth and that public policy carrots and sticks are both needed and justifiable to ensure it comes to pass.

On another matter, whose brainchild is IPv6+? I haven't heard of that one before.

Having IPv4 just for your public facing servers is a small expense, and within the private network you can still use private IPv4. The biggest pressure is to allow your servers to call out into the internet without an IPv4 address or a NAT. That's pressure on APIs, SaaS services consumed by backend servers, update servers, etc.

Maybe that's enough to remove the friction around IPv6 and make it "just work" to the point that everyone just keeps it on. Or maybe it doesn't and we get a divide where everything consumed by machines moves to IPv6 while content consumed by humans keeps preferring IPv4.
