All it takes is one big company like Amazon changing their services to IPv6-only and most of the world would be converted over in a month or two... but now I guess we know the reason WHY Amazon doesn't push such a policy.

A massive swathe of current gen devices don't even support it.

It won't be a month.

Microsoft announce changes much smaller than that 4 years out and still have to give extensions.

[–] [email protected] 19 points 9 months ago (1 children)

Seriously? How can any device call themselves current gen and not support something as basic as this? That's just embarrassing.

Android doesn’t support DHCPv6 lol

[–] [email protected] 3 points 9 months ago (1 children)

Why not? Isn’t there a dhcpd6 in Linux?

[–] [email protected] 2 points 9 months ago

Ugh... still? I knew the mail app had shitty support for it and had to create an IPv4-only dns entry for my mail server, I didn't realize the whole system was broken. Ah well, despite being an android user myself I would still place it in the bucket of "not modern" because there's really no excuse for something like this.

Getting plenty of local link and global ipv6 adresses on my pixel 7...

[–] Archer 1 points 9 months ago (1 children)

Probably via SLAAC. Android doesn’t follow the specifications for getting an individual DHCPv6 address

[–] [email protected] 1 points 9 months ago

Might be.
Honestly I couldnt be bothered with IPv6 and learning all the intricacies. Plus having borderline OCD for symmetry and order on random things and objects makes me actively dislike the whole 50 adresses per device thing.

But for real: Why even have an existing standard and not just use it at all.
This is basically the Pingu meme saying "Well, now I am not doing it. >:("

Like what though?

The last thing I have that doesn't support ipv4 from the hardware level is my Nintendo DS.

Everything else has the hardware capability, it's just never used or enabled in the software by default.

[–] abhibeckert 8 points 9 months ago* (last edited 9 months ago) (1 children)

it’s just never used or enabled in the software by default

...and most people who own those devices have never heard of IPv6 and don't know how to enable it. They just won't be able to access your website. If Amazon dropped support for IPv4, there wouldn't be anything i'd be able to do to deal with the fall out. I'm not going to send a technician to every single home of every customer I have. What I could (and would) do is move all my stuff off Amazon.

[–] [email protected] 0 points 9 months ago

this shouldnt be a.burden for users.

you can simply update a device to support it by default.

My smart TV from two years ago does not support ipv6, and it was fairly high end.

I was really trying about 5 years ago but there were just so many devices that don’t. My ISP still doesn’t

[–] [email protected] 2 points 9 months ago (1 children)

What manufacturer/operating system?

[–] AA5B 2 points 9 months ago* (last edited 9 months ago)

Vizio 65” OLED. Technically I don’t see anything saying yes or no on IPv6 but I didn’t find any relevant settings on the TV network config, nor do I see any IPv6 address on my router.

I did see an online post of someone saying similar, except the Chromecast functionality used IPv6

Wasn't 64 bit adoption largely driven by Microsoft deciding they weren't making a 32 bit version of their next Windows at one point? It seems it might take something similar.

[–] [email protected] 8 points 9 months ago

Microsoft supports 32 bit processors still with windows 10. They died out because it was becoming clear that 4GB of memory wasn’t going to be enough for applications, and the low margins on budget chips didn’t warrant maintaining 32 bit designs when the 64 bit versions would do and could still run the 32 bit software.

[–] [email protected] 6 points 9 months ago (1 children)

No, 64 bit was widely adopted long before windows cut support. Keep in mind a 32 bit OS can only use ~4GB of ram, and most systems have been shipping with more than that for many years now.

[–] [email protected] 1 points 9 months ago (1 children)

Towards the end of 32 bit’s life, physical address extension allowed operating systems to use more memory, often up to 40 bits worth, but still could still expose a 32 bit address space to user applications.

[–] [email protected] 1 points 9 months ago (1 children)

Yes, but that would only get the total up to about 5GB, which isn’t very much more.

[–] [email protected] 1 points 9 months ago

2^40 is a terabyte

[–] [email protected] 1 points 9 months ago* (last edited 9 months ago)

thats why dual stack exists. so older devices can still be used on an ipv6 network.

just give us a functioning ipv6 infrastructure, and the majority of home routers in the marlet will deal with it seamlessly.

so i want to know whats the damn holdup at this point?? my 3rd world country has it but big US players like carriers and amazon seemingly cant do it.

[–] [email protected] 12 points 9 months ago (1 children)

It would be a good start if AWS supported IPv6 on all their services in the first place. Everything enters through CloudFront so I don't need any IPv4. But AWS's own services don't have IPv6 in every region, so I still have to provision NAT gateways.

[–] [email protected] 4 points 9 months ago (1 children)

Yikes. I get free IPv6 for my servers through Hurricane Electric since my ISP doesn't provide it yet, I wonder if their service also works on AWS? I mean come on, if someone like Comcast can figure it out, why is it so hard for a major player like Amazon?

[–] [email protected] 4 points 9 months ago (1 children)

Lots of legacy networking I would assume.

Most services especially compute can get IPv6 so if all you have is EC2 instances you're good. S3 is usually fine, but I think when you get into Lambdas and especially the more niche services, those are IPv4 only, so you need some IPv4 addressing.

Ironically I've really been enjoying the massive IPv6 address space, makes numbering dozens of VPCs and subnets a whole lot easier. I don't get why it's not in huge demand especially larger customers.

[–] [email protected] 1 points 9 months ago

It is actually in demand by one big customer, the DoD. Amazon is pushing hard to get all its services IPv6 by EOY as of this year’s re:Invent. Something like 98% need to be in place for DoD contracts.

And they’re trying to force people over to IPv6 by charging them per public IPv4 address, so, hopefully that spurs the migration. Larger address counts/space is super useful.
