As it should. Date notwithstanding, I would actually enjoy if there was a manually induced latency penalty for "legacy IP" that needs to be manually turned off on Linux. I know some people don't care at all, but the internet was made to be addressable. IPv6 is the only shot we have to go back to that.

It will be a neat experiment, but I think most software will break and will remain broken indefinitely and then people will turn to LLMs to try to automate fixing all of it and that will turn into a mess just due to the sheer amount of changes required with little scrutiny.

great, now can we convince the rest of the internet to start adding AAAA records and ipv6 endpoints for things. Github is still a nightmare to use DNS64 and NAT64 to access those from IPv6 only machines.

Or all the Container based stuff that still falls flat with ipv6 only modes. Docker still shits the bed if you dont give it ipv4 unless you do a lot of manual overrides to things. A bunch of Envoy based gateway proxies fail on internal ipv6 resources in a k8s cluster that runs on ARM64.

There is just a bunch of nonsense you have to deal with if you choose the ipv6-only route

Dont get me started on CDNs like Bunny or Load Balancers as a service like those from Hetzner, UpCloud, etc that don't work with ipv6 origins.

Perhaps it's time to submit patches that allow building it without IPv6 instead. Countless hours of configuration meddling will be saved.

This reminds me of the ways the governments screw over people to force them to do things they don’t want to.

Not sure if you're taking the piss or just missed it but allowing build with either protocol alone is one of the genuine ideas in this joke:

> Maybe we don't get away with the actual deprecation and the warnings on use just yet, and maybe we won't even get away with calling the config option CONFIG_LEGACY_IP, although I would genuinely like to see us moving consistently towards saying "Legacy IP" instead of "IPv4" everywhere.

> But we should clean up the separation of CONFIG_INET and CONFIG_IPV[64] and make it possible to build with either protocol alone.
