I personally can’t find a reason to switch over on my home network.

I understand why v6 is necessary for the internet but I can’t reconcile it with my home network.

I tried a few times migrating over and it’s just an insane amount of work for essentially nothing… all the firewall rules, containers to subdomain mappings, all the wifi clients would get a completely new numbering scheme. And it changes when you change ISP if I understand correctly because your prefix changes.

It just seems insanely complex to me for no benefit. I have nginx as a proxy on ports 80 and 443 which dispatches the request to the right application based on the subdomain, and that’s it. I don’t understand what ipv6 would do for me in that context.

And most (all?) games or VoIP or other network applications all know how to deal with NAT by now.

With v4, I can have subnets and firewall rules so that my printer can only talk to local computers, or my tv only to my home assistant instance. Now idea how I’d move this all over to v6.

This is required by law. [0][1] Every ISP is required to be fully ipv6-enabled by the end of this year. The deadline has been pushed back multiple times , most recently due to covid. But this time it seems its going to stick. All lagging ISPs seem to have deployed v6 at this time. There has been a "National IPV6 Plan" in place since 2010, and full coverage has been pushed under that plan in stages. Anyone interested…

It seems it was in plans for a long time undetected, but then they committed to enforcing it when Jio took off.

Because there is no significant benefit to the consumer

It has: significantly cheaper internet access once providers have to charge extra for expensive v4 addresses, complex NAT solutions and gateways.

Significantly cheaper is a bit of an overstatement.

Savings are pretty much capped at one month of internet service, as that’s roughly what an IPv4 address costs.

Why is it so hard to pull off the same regulation in other parts of the world? It isn’t like supporting IPv6 is black magic…

We had the same in Brazil, scheduled per connection type (DOCSIS was first, etc). It's the only way IPv6 will happen, and more people should push for this.

There is no need to move your whole private network over to IPv6, although it might provide a good learning opportunity. You could start with enabling IPv6 for your nginx reverse proxy and make it listen on its IPv6 address. IPv6 has subnets too and firewalling is still possible, only NAT isn't needed anymore (which is good).

Edit: Reading your post again it sounds like you have mental model of either IPv4 or IPv6, when in practice it is often mixed. Each client can have an IPv4 and IPv6 address - even multiple ones! When you enable IPv6 on your router it gets a subnet from your provider and announces the prefix on your network. The clients then generate their public IPv6 address based on this announcement. Note: Even though they now have a public IPv6 address, the router's firewall should block incoming connections to it by default. That's the case for my router, but to be sure you should check it yourself for yours.

I work at a decent-sized ISP in Sweden, and we've been trying to get IPv6 to customers for over 10 years. It's hard. The way the Internet is built (many municipal broadband networks[0]) means there's middle networks that might not support IPv6 (the reason used to be "no interest" and "it's not a priority"). PTS is starting to show some interest[1], we'll see what leads to. [0] https://en.wikipedia.org/wiki/Municipal_…

That's kind of what I'm hinting at, the municipal entities assigned to handle the installation of fiber started this 20 years ago, which means that even 1Gbit is not the norm, the old 100Mbit connections are. I know a person that works at such a place and they have zero interest in upgrading their routers, because it would only cost money for the labour and equipment.

The flip side is that retail customers aren’t exactly clamoring to pay more for IPv6.

Your home network is part of the Internet, by definition. There is no difference between one part and another.

It’s useful for certain corporations to try to crush the end-to-end principle but there is no benefit in going along with their plans.

Because generally it would be a bad idea for the government to force certain technologies upon the private sector, even if in this case it might be fine.

In this case, it seems different because IPv6 is the kind of thing that I doubt any free market competitor would ever be able to supplant. Part of that is the nature of IPv6 itself, as it was designed to be as future proof as it could be. I just don’t see a competing protocol as offering any kind of substantial benefit.

Forcing micro USB and now USB-C on electronic devices has been one of the best ideas by the EU overall. Remember using ten different charging cables? Gone, due to a helpful piece of regulation by the government.

It isn't a good policy and if that is one of the best ideas of the EU then they have failed as a political project. 1. Corporations are exactly the tool we use to work out what trade offs of cost v. standardisation are best. Everyone is going to claim victory for a bureaucratic committee then a few years down the track we'll discover technology moves on and the regulation is force people to make stupid choices. Remov…

There are plenty of other good ideas coming from European unification. But standardizing the connector has certainly been a success. We already have 11 years of hindsight. And despite agreeing on micro USB initially, this hasn't stopped a smooth upgrade to the logical successor, USB-C.

The USB standard is messy, but I think there's been ample evidence that this is not because of the EU. Bluetooth is also very messy.

Point three is just nonsense, I got nothing to add to that.

This is why I won't enable IPv6 unless ISPs dramatically change how their hardware works. My ISP-issued modem+router doesn't even have a way to disable routing or automatic updates. I can test the firewall today, but what guarantee is there it'll just keep working?
