My website has a few hundred thousand users.

My development is completely user driven.

I get hundreds of feature requests and other emails regarding my site per month.

So far, not a single user mentioned IPv6.

So I never added an AAAA record.

The codebase has grown for over 10 years now.

God knows what subtle breakages would happen when IPv6 requests come in.

I wonder if I ever will add IPv6 or just leave the site running on IPv4 forever.

Anyone go out of their way to disable IPV6 on all their systems, even at the hardware level, like on routers etc? What's a good reason to avoid IPV6?

If you have a large estate of IPv4 addresses, the more ubiquitous IPv6 gets, the less they're worth.

Not there yet it seems:

Earlier quoted context omitted.

I just hope ipv6 doesn't have privacy nightmare that 1 device will always get 1 IP. Currently, the isp I use provides dynamic ip, so on every router restart my ip gets changed. If they starts to provide ipv6, I hope they give options to rotate it frequently, so toxic companies like meta, facebook, microsoft can't connect my device & ip.

It's sad how much has changed in the past 10+ years. I remember arguments advocating for ipv6 for exact reason. 1 device per 1 ip. Back then, it was seen as something great. I agree with what you said. It's just interesting how it illustrates how different things are now.

I remember a bunch of people being horrified by the idea of 1 device per IP. I think it's more a matter of who you were around then the group changing their mind, but maybe that happened too.

I sure wish Starlink supported IPv6. They're a brand new ISP planning for millions of customers and decided from the start they couldn't get enough IPv4 addresses for everyone. Fair enough! But we're stuck with Carrier Grade NAT and it is a drag. On Starlink it's impossible to host a server socket directly, which makes any peer to peer networking a PITA. Geocoding IP addresses doesn't work so I have to bend over back…

Get a raspberry pi, set up two vlans, run wireguard, and send 100% of your uplink traffic to a remote vpn endpoint.

This gets you off their IP, and also has the added benefit of not letting them analyze your traffic.

“In December 1998, IPv6 became a Draft Standard for the IETF,[2] which subsequently ratified it as an Internet Standard on 14 July 2017.” 40% adoption after 25 years? Really highlights how terrible IPv6 is in terms of backwards compatibility. What we needed was an internet protocol with the benefits of IPv6 that runs as an extension to the IPv4 stack. The current approach to duplicate everything into IPv6 is wasteful…

Despite the downvotes you are right. IPv6 replaces IPv4 rather than building on top of it and this really harmed adoption.

Are there any advantages to IPv6 other than more addresses ?

I just hope ipv6 doesn't have privacy nightmare that 1 device will always get 1 IP. Currently, the isp I use provides dynamic ip, so on every router restart my ip gets changed.

It rotates about once a day in most operating systems. Called ipv6 privacy extensions. This is of course defeatable, but it provides a nice black hole for a device. It moves on and you can't connect to it anymore.

And adds 20ms+ latency, another complex point of failure, and potential problems depending on the reputation of the IP address block of wherever you're hosting the endpoint. I've used VPNs to smooth over various Starlink problems since I got the service and it helps but it's not a great solution.

Having a non-residential IP address is likely to get you blocked from services like Netflix.

It would be nice if there were some way to decouple connectivity from addressing, without becoming a second-class citizen of the internet.

A local ISP told me that they want to get into IPv6 as soon as possible. NATs are getting costly and moving just YouTube traffic to IPv6 would actually help a lot.

The problem is with end user devices that do not use a stable DUID and when the client hits the reset button, it changes. We are probably going to work around this by responding from the closest hop and taking the MAC into account.
