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.

Good stuff (both the joke and the genuine proposal of splitting the config options for IPv4 and IPv6).

IPv6 vs. 4 is like Python 3 vs. 2, just worse.

The best pranks are the ones that succeed to rattle an individual. Build it!

I suppose this will lead to a classic torvalds rant. I will be watching r/linusrants

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.<p>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.<p>There is just a bunch of nonsense you have to deal with if you choose the ipv6-only route<p>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.<p>Source: Trying to run a ipv6 only self-hosted box on hetzner.

We’re so close guys! Another 25 years and we might almost be there!
